Thank you so much for the great tutorial! I've also noticed the data was gone a few months ago, now I saw that it was back and I could do the tutorial and I've learned so much :-)
Really helpful video. Would you use these for most images or is this unique to Nebula? Also how do you reduce the size of the image that you mention at the start. I'm a bit clueless. As the file size is massive.
Thanks Matt. My intention was to teach you the tools and their uses so you can take them to Lunar or galaxy photos as well. What levels do, why curves do etc. As for the file size I can't remember off the top of my head right now and I'm at work. There's a comment around here somewhere where the same question was asked. So if you can find that before I get home to look it up, that could give you your answer :)
I downloaded GIMP but it did not open the RAW file so used Darktable plugin but it opens another window which does not seem to have the same tools as GIMP's main window! any tips?
WoW. This was very complete and included a test file so we could edit along with the video. This man is a true teacher. Liked and subscribed. Please do a tutorial using Gimp on a galaxy from a raw stacked or otherwise image. It is hard to know how to bring out the correct detail in a galaxy like m31 or m33 Triangulum or the m101 Pinwheel. This would be very helpful since Gimp is free and a very good editor. Thanks again. Harry
this much better then Astropixelprocessor i had problems getting setup and at least i can try learn this one with dslr canon this gimp program at least it's free.
I just started in astrophotography 6 months ago and this was so helpful. I have been frustrated as there is so much to learn in this hobby. This is the first video I have found that explained in plain English what is supposed to be done during processing after DSS. Thank you for being so easy to listen to and to follow at your pace. I walked through this with you and came out with a decent Rosette Nebula (one of my stacked images that red applied to). I will watch many more times as at the end with the brush and contrast parts I think I finally popped a blood vessel in my brain : ) At 58 years old I really needed to see this to give me hope that I "will get it" some day. Thank you again.
You are very welcome. Thank you for the words about the tutorial! I hope to see your rosette nebula someday as well! My main intention was to go at a steady pace and clarity. I also try to explain what things so rather than just "do this", as if you know the system you can then apply it better than just being told to do it
T Tiago Ramos 10 months ago @AstroFarsography Thanks for this video using Gimp. I'm new to Astrophotography and this is powerful for me. Im in light polluted chicagoland so anything on removing LP Gradients would be great. Im using a dual band LP filter but still fighting the LP Gradients. I see a Gradient Tool but cant figure out how to use it.
I picked up my first astrocamera 8 months ago (ASI533MC) and have been puzzled about post-processing ever since. Your's is the first video I've seen that walked me through the steps and I cannot tell you how much it's helped me to understand what to do. Thank you for a great video.
Hey AstroFarsography, I just wanted to thank you for this tutorial! I've been dabbling in amateur astrophotography for a few years and I exclusively use GIMP for processing. Every single time I process a new image, I open up this video and watch/listen as I go through my processing. I've watched this video dozens of times throughout the last few years, and I'll continue to do so. So thank you so much, you've helped me immensely!
Hey mate thanks for your comment, that's really nice to hear how you've benefitted from my video, happy to have been able to help you out! All the best and clear skies mate
Hi AstroFarsography. I downloaded Gimp a few weeks ago as I am finding Pixinsight lacking in some of the tools PS can accomplish and GIMP is the best alternative to Photoshop. Thanks for the effort and posting this tutorial.
@@AstroFarsography I have done quite a bit mainly with the Altair 183c TEC and processing in PI. I have a lot of gear so playing with the different ones (esp. cameras) is an entirely different learning curve. The skies cleared so I am getting ready to image with a small camera Mallincamsky DS 287c. I did some lunar and Saturn photography in October. Results were quite good considering the poor seeing conditions ( Orion 7" f/15 Mak., Mallincamsky DS287c camera, made a short video then processing in Autostakkert and Registax. First foray into planetary/ lunar photography.
really helpful, I know it seems obvious to you, but when learning people saying "right click here", "now I'm pressing this" etc makes it so much easier to follow when I'm trying to learn by doing it with you. keep it up!
Can you make the image available again? I'm getting a file 404 error on the link. Thanks (I know this is an older video, so I understand if you don't have it available any more, but thought I should ask).
Another great video! I have not used PS, but I’ve seen some videos of it in action. Gimp looks pretty much like PS, but with the advantage of being free. I’ll give it a shot. Looks like a good complement for Pixinsight.
Fantastic example using GIMP. I made some typed notes which amounted to about 50 steps so I could apply your method to my next image. GIMP is my preferred editor since I'm trying to avoid PS and PI if I can. Many thanks for a really nice image and very well done tutorial!
I would love and Andromeda tutorial to be one of your next. When I tried the workflow you've showed for the North American Nebula I immediately ran into a problem I don't know how to solve. In making the Star Mask, selecting stars by color also selects the core of the galaxy. When I try to unselect it, Gimp unselects all of the stars of that color selection. If I'm going to try to bring out the faint parts of the galaxy, it seems as if I should not include the core in the Star Mask, but I don't know how to do that.
Hey Homer. I have some M31 data I can do this with. I intend on doing a galaxy tutorial so keep tuned. I'm in the middle of moving house currently but it's certainly on my radar to do!
Thank you so much for this. I have been searching for a good AP editing tutorial using GIMP and masks specifically. You do it in a way that is super easy to follow. I am a complete newbie to AP generally so I am learning everything from using a camera to processing. . . and just in case it was easy I use linux so Siril seems to be my only option for the stacking bit, unless you know better? Once again thank you!
That's not a problem, glad to have been of help! 🙂 And welcome to the hobby. It can be frustrating at times but it's the best thing out there 😁 and sorry, I don't know of any software for Linux 🙁
@@AstroFarsography Frustrating but very rewarding when it works out :-D Siril seems OK for the registration and stacking and I think I have that sorted now. It really is all about the processing you demonstrate in this vid. I have Darktable and something called PyAstro hooked up to GIMP as well. Darktable has some nice features for handling RAW images and allows me to open them with GIMP. PyAstro has some routines created specifically for processing too. So I think I have all the tools needed - it is just the firmware in my head that is old and slow lol
10/10 tutorial, my man! I just got back into astrophotography, and the only thing I remembered was how to polar align and stack images. This tutorial is a huge help!
Hi, I did my first Astro shoot today early morning. And the files are FITS. So i am following what you are doing, and now at the start, after First Level, i have come to First Adjustment. Here when i select Windows, Dockable Dialogue, and select Histogram, then click on Value, and on the drop down Menu, non of the values are settable, here i am supposed to select RGB, but even R, G, B are not selectable. Also in the 22KB Jpeg, i mages from the ASI294MC PRO, the Lagoon Nebula has all the rich red colours, but the FIT file which is about 23MB, is totally grey. even after landing in GIMP 2.10. What am i doing wrong. I am using a iMac. am i supposed to convey FIT to some other format. I tried that online converter, to TIFF and same result, all Grey. The Nembula Color tat is visible in the 22 KB Jpeg image is just not there. .
Hi Ramesh, how are you stacking your images? What program? It sounds like they're not being debayered so they're gray. It requires debayering during the stacking process and that will then yield you a colour image
@@AstroFarsography Ok, is there a video link you could share that explains to dumb guys like me, how to debayer, I get FITS file as single shots, and also a Stacked Image in FITS, from the ASI Air PRO.
As a noob I am very thankful for this walk through, but I am also very frustrated with the lack of explanations. As an example, at around 12:50-13:10 a layer suddenly appears after hearing you tap the keys on your keyboard. It has taken me 2 hours to get 13 minutes into the video going back and forth trying to understand what you are doing since there are no captions of explanations for a lot of the things you do, but this move is like the trick of an illusionist. Maybe I get it if I once again back up to the last time you made a selection via colour. What do you do beyween 12:50 and 13:10 to create the new layer? Thanks in advance. Ps. I am very thankful for helping me understanding, despite it being a bitr of hard work ;)
This is probably the most informative astrophoto editing video I have EVER seen - BRAVO! Most go over PS but why? We amateur astronomers almost exclusively use freeware/shareware like Stellarium, SharpCap, Deep Sky Stacker, etc. etc. - why do most of us use PS? I HATE the subscription model where you must have an internet connection and maintain a subscription to use software. I stay away from all "RENTWARE". Again thanks a TON for this - I would like to see more GIMP tutorials. Can you do one on solar imaging?
Thanks so much Lane this is a very wonderful comment to read. I enjoy being able to pass on the knowledge especially the free software. I'm just glad that it's helpful 😊😊😊
Great video. I just downloaded GIMP and wanted to follow your procedures with some practice on a photo I took of the Orion nebula. Unfortunately I ran into a road block right out of the gate, LOL. In the first step that you take you click on the menu option called colours in the list of options in the upper left hand corner of your main menu. My opening screen does not have any of those options above the tool menu in the left-hand column. Is there an option that I need to enable that I am missing? I would appreciate any help you can provide.
A absolute beginner here. Does this tutorial apply only for deep sky photography? I've taken a photos of night sky, the stars are seen quite well in the photo, when I start to edit it, the photo becomes just very foggy, so much noise appear.
Widefield is slightly different as you have more to deal with, but generally levels and curves are still going to be your best friends. This fog you mention, is it in just one specific place like a big circle?
@@AstroFarsography No, it cover the pic overall, like a very bad filter or sth. Maybe the image doesn't have enough information..I don't know. When I made the pic a bit lighter on levels, I could see a hint of Milky Way, but just a faint hint
Nice tutorial. Looking for a tutorial to process images in GIMP using a monochrome camera. I would like to see processing tips after LRGB images are stacked and co-registered and brought into GIMP.. These tutorials show processing tips for images obtained from a DSLR. Helpful to a point, but monochrome images opened in GIMP will have a different workflow. Thanks in advance.
@@bigone520 that's interesting then. I purposely had mine low as I know the monitor I use is quite dark. But still that you can see much more data is interesting!
Wow, have only just down loaded Gimp..Have a lot to learn, but your video will help and encourage me through my journey. Thank you. Have also subscribed. Right, let's watch that again 😄
Thanks for the videos!!! They are so helpful. I recently bought a H-alpha filter for my dslr. There just isn’t a lot of information on the internet about processing and combining the H-alpha and RGB in gimp. I’ve seen some videos on how to do it in photoshop, but nothing for gimp. I would love to see a video on that. Any advice I would appreciate.
Using your video I came out with this for a literally first timer! Thanks a million. drive.google.com/file/d/1txrIaKYblejjlc9vwIrc5reomxnQOrk6/view?usp=sharing
Free programs like "Deep Sky Stacker" do the job so well, I have think doing it manually would be entirely for the challenge or some odd edge case like combining different focal length / fov shots or something
I seem unable to control or understand when the output of deep sky stacker is taken into gimp as a grayscale, and when it is taken in with color. My camera is a one shot cooled color astrophotography camera, and sometimes the parameters I use in deep sky stacker lead to an output file in gimp with color and other times it’s grayscale! This is for the same images. Sometimes color in gimp and sometimes grayscale. Frustrated and feeling stupid… Can you help?
I have been looking for a way to crop a small set of individual registered images such as an LRGB set in Gimp when I bring them in as layers...would you please make a video or tell me how to do so...thank you😊🌈
Nothing went right for me. Not sure if its my lack of a light pollution filter, my camera, the file type, or the fact im using live stacking but nothing worked. I tried Horsehead and Pleiades.
Hi friend. I’ll try some of these techniques. Thank you! But I’m having a lot of difficulties on treating my photos. I don’t know if I’m taking them the wrong way or don’t know how to edit them. I have one here that may be beautiful but can’t isolate the noise.
Thanks for making this tutorial as there are not many out there for us wanting to learn GIMP with astrophotography. Could you make another with less steps, less layers and no keyboard shortcuts. Thanks.
I have an image of M27, Dumbbell Nebula and really struggling with getting the white/blue gases to resolve in the image, can you suggest best way to do this?
Good tutorial but for a newbie like me.....you moved to fast. I really don’t know the fundamentals to gimp and with masks do and their purpose and how to do them. Is there a video on how to learn the fundamentals of gimp or photo processing in general?
Sorry but really cannot get the star mask side of this to work. Has this changed since you made the tutorial because I appear to be following you but not getting the same result!
Very helpful , just starting out in astrophotography . Just learning how to process pictures is a lesson , let alone anything else . Would like to see a planet process in gimp . 👍
A million thanks for posting this video... I'm a beginner astrophotographer and not graphics processor. For the last 3 years I have been trying hard to process my poor quality captures with GIMP but couldn't get it to work. I'll not be able to get PixInsight for the next couple of years. I'm not finding any good tutorials online to process astroimages with GIMP. I request you to please post more videos of processing astroimages with GIMP. Also if you know any tutorials online to process astroimages then please let me know. Once again many thanks for the video... :)
You are most welcome! When I had just begun processing was the hardest part to be sure! I do intend on making more tutorials in the future for GIMP and Photoshop. I couldn't find too many online tutorials either when I began. Hope to see some of your work from following my tutorial! 😁
Just subscribed - keep up the good work. Really pleased that someone is taking the time to help others obtain the best from Gimp as the only editor I have paid for is AstraImage (40 U.S. dollars roughly). PS, PI etc, might be alright but then you have to pay and to spend the time learning and I would much rather be outside at the telescope than sat in front of a computer. After being greatly disappointed with Windows 10 and the trouble it has caused me last year I have migrated to Linux on another machine so tutorials on Gimp are received with much gratitude. Something on Siril for stacking (free and on Linux) might be of benefit to people. Looking forward to catching up on your other vids now - thank you.
Thanks for the support and the comment! Yes this hobby can be expensive enough before needing the processing software also! I have a few other GIMP tutorials in mind that I need to rehearse and record but I'll continue with them! As for the stacking program, j don't run Linux so unless it's available on Windows j won't be able to use it regrettably.
Thanks Graham, glad to have helped! And thank you for those kind words, I seem to be picking up a bit more traction now and I'm awfully grateful about it 🙂
Nice tutorial and walk through the features of GIMP which are useful for Astrophotography. One question though. Was there a bit of ringing of the stars? Or was that the outline mask? Also how do you save the final image?
Thank you Dilip. The ringing in the stars would've been from my rough and not fine tuned selection process for making star masks. So if you take your time more with it and really get those selections nice and sorted then you'll be able to eliminate the ringing. I save the final image as a TIF to keep its quality, or as a GIMP working file. When I'm ready to export and share I just save it as a JPG.
@@AstroFarsography Thanks for putting together a GIMP workflow and demo. I have been thinking of using GIMP as I cannot justify using Paintshop, Etc. due to cost. I look forward to seeing your updated work and techniques.
neat. two comments and a question: you mentioned there is a larger image, so if i wanted to reproduce what you had, this is going to be very hard. meaning, the steps, levels etc. are not encoded in gimp in reproducable steps I believe. that's a shame. I don;t know if darktable can do all the things you did, but if it did, that would be the way to do this. This way all the steps are in an xml file, all the procedures have parameters. My second comment is your picture is already in a single colorimage it seemed. what if you had 3, or heavens forbid, 4 or 5 filters B/W images, that's a nice new challenge. I've heard of a photoshop plugin that can do this, at the time gimp could not do 16 bit, and you need 16bit to really do that kind of work. So would be neat to see if one could reproduce that workflow. It's called the FITS liberator. I believe the STSCI picture are or were made with this. FInally a question: the image is very red, in fact, it's red. but i saw you shift the range to make red range closer to be matching the green and blue? so I would have expected more colors than red.
Hey there thanks for the comment I believe it'll be fine if you use a bigger picture. I didn't mean for this tutorial to be a "follow my exact steps" style and more so I try to teach the tools so you can go apply them to images the size of a passport picture, or a billboard :) Yes making a composite image in GIMP is another challenge to make LRGB or SHO images etc. I used s one shot colour picture here because it's what i suspect would be more common. I have got composite tutorials in the works coming up And yeah, the final image is really red. I somewhat blame my old monitor for that 😀 even though I adjusted colours and such I'm not sure why or how it's still so red 😅 I've improved myself now and I believe I could do much better these days
You have great teaching skills. 👍🏽 You need more Gimp and DSS. I want lr but some of these high prices make it hard. 300 for program or new piece of equipment . Great job thought 👍🏽👍🏽👍🏽
Thanks Greg, more tutorials on their way! I understand, when you need software but it's the same price as a nice bit of hardware! Adobe do Lightroom and Photoshop as a pay monthly bundle the last time I checked
@@AstroFarsography OK will try again. Just 7 mins into your tutorial so far, looking very good, new to all this so can’t wait to try out. Much clearer than others I have tried to follow. Not seen anything so far on image so apologies if silly question, but what did you take image with and settings. I have some pics of Orion from a cannon Eos 1200d, settings up to about 8 secs, iso 1600 and wide aperture Thanks again
I really like what you are doing but I'm pretty new to GIMP and sometimes you go so fast that I have a very hard time seeing what you are doing. If you would slow down when you select tools etc it would really help.
Hey all. I had many messages saying the data link wasn't working. I've since fixed that, so enjoy! Thanks for letting me know!
Thank you so much for the great tutorial! I've also noticed the data was gone a few months ago, now I saw that it was back and I could do the tutorial and I've learned so much :-)

This was really, really helpful, thank you! I've been using GIMP very basically for years, I've learned so much from this video!
As a noob I am very thankful for this walk through, but I am also very frustrated with the lack of explanations.
As an example, at around 12:50-13:10 a layer suddenly appears after hearing you tap the keys on your keyboard. It has taken me 2 hours to get 13 minutes into the video going back and forth trying to understand what you are doing since there are no captions of explanations for a lot of the things you do, but this move is like the trick of an illusionist. Maybe I get it if I once again back up to the last time you made a selection via colour.
What do you do beyween 12:50 and 13:10 to create the new layer?
Thanks in advance.
Ps. I am very thankful for helping me understanding, despite it being a bitr of hard work ;)
This is probably the most informative astrophoto editing video I have EVER seen - BRAVO! Most go over PS but why? We amateur astronomers almost exclusively use freeware/shareware like Stellarium, SharpCap, Deep Sky Stacker, etc. etc. - why do most of us use PS?
I HATE the subscription model where you must have an internet connection and maintain a subscription to use software. I stay away from all "RENTWARE".
Again thanks a TON for this - I would like to see more GIMP tutorials. Can you do one on solar imaging?
Thanks so much Lane this is a very wonderful comment to read. I enjoy being able to pass on the knowledge especially the free software. I'm just glad that it's helpful 😊😊😊
Great video. I just downloaded GIMP and wanted to follow your procedures with some practice on a photo I took of the Orion nebula. Unfortunately I ran into a road block right out of the gate, LOL. In the first step that you take you click on the menu option called colours in the list of options in the upper left hand corner of your main menu. My opening screen does not have any of those options above the tool menu in the left-hand column. Is there an option that I need to enable that I am missing? I would appreciate any help you can provide.
Great presentation. Discussion of star masks was WAY TOO FAST. Everything else was clear.
Great Tutorial! Thanks for sharing.
A absolute beginner here. Does this tutorial apply only for deep sky photography? I've taken a photos of night sky, the stars are seen quite well in the photo, when I start to edit it, the photo becomes just very foggy, so much noise appear.
Widefield is slightly different as you have more to deal with, but generally levels and curves are still going to be your best friends. This fog you mention, is it in just one specific place like a big circle?
@@AstroFarsography No, it cover the pic overall, like a very bad filter or sth. Maybe the image doesn't have enough information..I don't know. When I made the pic a bit lighter on levels, I could see a hint of Milky Way, but just a faint hint
Good tutorial, and nice picture. Thanks!
Thank you SO very much. I'm a total GIMP NewBoy and this really helps. Cheers.
Thanks for the data & tutorial Ruzeen. I had an excellent tutorial in PS using M45 by A.V. Astronomy.
Nice tutorial. Looking for a tutorial to process images in GIMP using a monochrome camera. I would like to see processing tips after LRGB images are stacked and co-registered and brought into GIMP.. These tutorials show processing tips for images obtained from a DSLR. Helpful to a point, but monochrome images opened in GIMP will have a different workflow. Thanks in advance.
Hello Ruzeen.
This video is my base in post-processing, in which
appreciate.
Can you make a video with the Gimp Astronomy Plugins? Thanks
On my first levels adjustment I get a lot more data showing .. about 12mm on the levels colour adjustment and I haven't even touched it
Hmm that's an interesting one. You might be able to skip doing the second levels adjustment then if it's showing enough data
On your vid at 1.10 you can only see a bit of data there .. I see about 12mm
@@bigone520 that's interesting then. I purposely had mine low as I know the monitor I use is quite dark. But still that you can see much more data is interesting!
I see data from the beginning of the letter E on levels on the adjustment level screen..
@@bigone520 not sure then. If it's untouched I don't know why you'll be seeing the data spike that far up the slider 🤔
Wow, have only just down loaded Gimp..Have a lot to learn, but your video will help and encourage me through my journey.
Thank you. Have also subscribed.
Right, let's watch that again 😄
Thanks for a great tutorial!
Awesome tutorial. I am about to start astrophotography and getting hold of some basics. This has been very insightful and motivating. Thanks a lot.
Thanks for the videos!!! They are so helpful. I recently bought a H-alpha filter for my dslr. There just isn’t a lot of information on the internet about processing and combining the H-alpha and RGB in gimp. I’ve seen some videos on how to do it in photoshop, but nothing for gimp. I would love to see a video on that. Any advice I would appreciate.
Using your video I came out with this for a literally first timer! Thanks a million. drive.google.com/file/d/1txrIaKYblejjlc9vwIrc5reomxnQOrk6/view?usp=sharing
Hello. Subscribed. Thnks
How do you make milky way stand out in night shots on GIMP? Thanks
Hi ! Thank you for this video. May i know how you did this photo ? With and DSLR or an astronomical camera ?
You really helped me to avoid buing into Adobe. I always didn't know hot to fether the colour selection. No I know. Thx a lot!
Do you have a tutorial on how on to stack images in gimp ? Thanks! Simon
Manually stacking? No, but I can look into this :)
@@AstroFarsography thank you !
Free programs like "Deep Sky Stacker" do the job so well, I have think doing it manually would be entirely for the challenge or some odd edge case like combining different focal length / fov shots or something
I seem unable to control or understand when the output of deep sky stacker is taken into gimp as a grayscale, and when it is taken in with color. My camera is a one shot cooled color astrophotography camera, and sometimes the parameters I use in deep sky stacker lead to an output file in gimp with color and other times it’s grayscale! This is for the same images. Sometimes color in gimp and sometimes grayscale. Frustrated and feeling stupid… Can you help?
I have been looking for a way to crop a small set of individual registered images such as an LRGB set in Gimp when I bring them in as layers...would you please make a video or tell me how to do so...thank you😊🌈
Nothing went right for me. Not sure if its my lack of a light pollution filter, my camera, the file type, or the fact im using live stacking but nothing worked. I tried Horsehead and Pleiades.
Hi friend. I’ll try some of these techniques. Thank you! But I’m having a lot of difficulties on treating my photos. I don’t know if I’m taking them the wrong way or don’t know how to edit them. I have one here that may be beautiful but can’t isolate the noise.
Thank you so much! This was really helpful in getting the galactic center of my milky way shot to really pop. Cheers!
Thanks for making this tutorial as there are not many out there for us wanting to learn GIMP with astrophotography. Could you make another with less steps, less layers and no keyboard shortcuts. Thanks.
25:30 "I'm not used to GIMP" means I have no chance. That was magic, but you showed us how...Thank you.
I have an image of M27, Dumbbell Nebula and really struggling with getting the white/blue gases to resolve in the image, can you suggest best way to do this?
Good tutorial but for a newbie like me.....you moved to fast. I really don’t know the fundamentals to gimp and with masks do and their purpose and how to do them. Is there a video on how to learn the fundamentals of gimp or photo processing in general?
Very detailed, just looking for someone to walk us rookies through the basics…
Sorry but really cannot get the star mask side of this to work. Has this changed since you made the tutorial because I appear to be following you but not getting the same result!
Still have the data for this tutorial? The link isn't working. Thanks...
Very helpful , just starting out in astrophotography . Just learning how to process pictures is a lesson , let alone anything else . Would like to see a planet process in gimp . 👍
This is a great and detailed video for gimp. Thank you so much for showing this.
Those this tutorial also works with processing galaxies since i am trying to practice processing galaxies also?
i get funny halos when i create star masks. I would like to see more examples / explanation of layers and masks.
I wanted to thank for your video on using gimp. I am very new to astrophotography
totally lost me after about 40% of it. why all the deselecting.youre going too fast as well.slow down
sorry to say, this did not help very much i did exactly what you said ended up with a very black image
A million thanks for posting this video... I'm a beginner astrophotographer and not graphics processor. For the last 3 years I have been trying hard to process my poor quality captures with GIMP but couldn't get it to work. I'll not be able to get PixInsight for the next couple of years. I'm not finding any good tutorials online to process astroimages with GIMP. I request you to please post more videos of processing astroimages with GIMP. Also if you know any tutorials online to process astroimages then please let me know. Once again many thanks for the video... :)
You are most welcome! When I had just begun processing was the hardest part to be sure! I do intend on making more tutorials in the future for GIMP and Photoshop.
I couldn't find too many online tutorials either when I began. Hope to see some of your work from following my tutorial! 😁
Very good video, would just suggest you slow down mouse selections etc to give more time to understand.
Just subscribed - keep up the good work. Really pleased that someone is taking the time to help others obtain the best from Gimp as the only editor I have paid for is AstraImage (40 U.S. dollars roughly). PS, PI etc, might be alright but then you have to pay and to spend the time learning and I would much rather be outside at the telescope than sat in front of a computer. After being greatly disappointed with Windows 10 and the trouble it has caused me last year I have migrated to Linux on another machine so tutorials on Gimp are received with much gratitude. Something on Siril for stacking (free and on Linux) might be of benefit to people. Looking forward to catching up on your other vids now - thank you.
Thanks for the support and the comment! Yes this hobby can be expensive enough before needing the processing software also!
I have a few other GIMP tutorials in mind that I need to rehearse and record but I'll continue with them!
As for the stacking program, j don't run Linux so unless it's available on Windows j won't be able to use it regrettably.
Superb explanation with clear instructions. Thank you very much indeed. You deserve a much bigger subscription/audience.
Thanks Graham, glad to have helped! And thank you for those kind words, I seem to be picking up a bit more traction now and I'm awfully grateful about it 🙂
Nice tutorial and walk through the features of GIMP which are useful for Astrophotography. One question though. Was there a bit of ringing of the stars? Or was that the outline mask? Also how do you save the final image?
Thank you Dilip. The ringing in the stars would've been from my rough and not fine tuned selection process for making star masks. So if you take your time more with it and really get those selections nice and sorted then you'll be able to eliminate the ringing. I save the final image as a TIF to keep its quality, or as a GIMP working file. When I'm ready to export and share I just save it as a JPG.
@@AstroFarsography Thanks for putting together a GIMP workflow and demo. I have been thinking of using GIMP as I cannot justify using Paintshop, Etc. due to cost. I look forward to seeing your updated work and techniques.
Brilliant , this has helped me a lot , thank you. Yes another on the moon would be great.
Awesome. Thanks for your help!
dear friend i wish i could get these steps in turkish from somewhere written
I got lost lol my image didn’t start out black and it just looked complicated
Very good tutorial, many thanks!
neat. two comments and a question: you mentioned there is a larger image, so if i wanted to reproduce what you had, this is going to be very hard. meaning, the steps, levels etc. are not encoded in gimp in reproducable steps I believe. that's a shame. I don;t know if darktable can do all the things you did, but if it did, that would be the way to do this. This way all the steps are in an xml file, all the procedures have parameters.
My second comment is your picture is already in a single colorimage it seemed. what if you had 3, or heavens forbid, 4 or 5 filters B/W images, that's a nice new challenge. I've heard of a photoshop plugin that can do this, at the time gimp could not do 16 bit, and you need 16bit to really do that kind of work. So would be neat to see if one could reproduce that workflow. It's called the FITS liberator. I believe the STSCI picture are or were made with this.
FInally a question: the image is very red, in fact, it's red. but i saw you shift the range to make red range closer to be matching the green and blue? so I would have expected more colors than red.
Hey there thanks for the comment
I believe it'll be fine if you use a bigger picture. I didn't mean for this tutorial to be a "follow my exact steps" style and more so I try to teach the tools so you can go apply them to images the size of a passport picture, or a billboard :)
Yes making a composite image in GIMP is another challenge to make LRGB or SHO images etc. I used s one shot colour picture here because it's what i suspect would be more common. I have got composite tutorials in the works coming up
And yeah, the final image is really red. I somewhat blame my old monitor for that 😀 even though I adjusted colours and such I'm not sure why or how it's still so red 😅 I've improved myself now and I believe I could do much better these days
You have great teaching skills. 👍🏽 You need more Gimp and DSS.
I want lr but some of these high prices make it hard. 300 for program or new piece of equipment .
Great job thought 👍🏽👍🏽👍🏽
Thanks Greg, more tutorials on their way!
I understand, when you need software but it's the same price as a nice bit of hardware! Adobe do Lightroom and Photoshop as a pay monthly bundle the last time I checked
Good work. Nicely paced and clearly spoken.
very very clear tutorial, thanks so much
Do most of your images start black like that? If so, why is that?
A superior tutorial! Thanks!
Wow this is so cool, thanks for sharing this awesome Data!
I would like to see a milky way photo processed on Gimp
Hi, can't get the data to download, is it still available ? Cheers Richard
Should still be! When you click the link it will say can't display file type and in the top right should be the download button
@@AstroFarsography OK will try again. Just 7 mins into your tutorial so far, looking very good, new to all this so can’t wait to try out. Much clearer than others I have tried to follow.
Not seen anything so far on image so apologies if silly question, but what did you take image with and settings. I have some pics of Orion from a cannon Eos 1200d, settings up to about 8 secs, iso 1600 and wide aperture
Thanks again
@@AstroFarsography worked
I really like what you are doing but I'm pretty new to GIMP and sometimes you go so fast that I have a very hard time seeing what you are doing. If you would slow down when you select tools etc it would really help.
Thanks for the feedback, next time I'll go slower :) Hope it helps none-the-less!
awesome this is just what i was looking for!
are we able to do the same with starnet software and GIMP?
