That means a great deal coming from you, thank you so much! I'd love to have touched upon some more of the features in your great program but felt this was enough to get someone started without things becoming confusing for a beginner :) Thank you again for taking the time to comment, I feel a bit starstruck after using Siril so long! Luke
One year on since you made this tutorial Luke I watched it for the 1st time after someone mentioned how good it is. I still like DSS to stack my images but love this. I also found it great to then save as a .Tiff file and finish using Photoshop and Starnet etc. A really easy to understand tutorial 👍
I'm just starting out in astrophotography, a bit late in life but hey, you're never too old to learn! I have been looking at processing software but I've been having a hard time sorting out which one to try/use/get confused with. I've looked at a lot of tutorials and I'm a little bit sick of the "I know what I mean so everyone must know what I mean" attitude that a lot of people have. Now, I appreciate that they're trying to help but having done a bit of teaching/instruction in the past I'm very conscious of where points are not being made well. This 16 minute tutorial has made my mind up to not splash out on Pixinsight just yet or APP but to give Siril a go. Thank you for a clear and simple explanation of how to start using this tool. It's very much appreciated and for sure, a more in depth one when you have the time will be appreciated even more. I subscribed a few days ago, I like your style. :thumbsup:
Hey! Thank you so much for your well thought out comment, it's very interesting to hear feedback from you especially given that you've given tuition yourself! :) I'm very happy that I was able to help in any way with this video, and I do really think that Siril is a wonderful program so I'm sure you'll get to grips with it in no time! 👍 Thank you for the subscribe, the support is hugely appreciated, and regarding starting out - you're absolutely right, you're never too old to learn and give new things a shot, I think the fact you are here researching such subjects just shows that you'll have a leg up on many other beginners right from the start! :) Thank you for your time, Clear skies and good luck! Luke
Stumbled across your channel after trying to find a tutorial of Siril (which I run on Linux), so nice to hear an English tutorial for once that explains as they go rather than just doing stuff and confusing the shite out of me, got another subscriber mate from not so sunny Yorkshire.
Hey Jason! Great to hear from another Yorkshire bloke mate! :-) Really chuffed that you found the tutorial useful, that's the best thing I could hope to hear! Thanks for watching and for subscribing mate! - All the best Luke
Brilliant tutorial and walkthrough -- made my first ever image of the Orion Nebula (and Running Man!) look better than I could've imagined. Thank you!!!
Excellent tutorial Luke. I have been using DSS for stacking & Photoshop for all my image processing, I think this will be a brilliant piece of software to compliment PS while I continue to develop my processing skills and until I am ready to possibly invest in PixInsight. I didn't even know this software existed. I have only recently come across your channel and it has been an absolute goldmine. Excellent work, keep it up buddy 👍
That's awesome to hear! - I'm really glad to have shown you another option for processing :) By the way, thank you for taking a look at my channel, I appreciate your time! 👍👍 Clear skies, Luke
This was so helpful in creating my first higher end image from a large telescope. What a difference using this versus just photoshop. Thank you for this.
Thank you very much well explained. Trying to get trapezium stars.. and your video helped alot.. to me orion needs to include these 4 stars as well as the periphery. still learning and now i know, thanks to your clear explanation and guidance on how to get better at this. Thanks
Great video and a wonderful help tutorial, best one i've found so far. The 2nd time I followed your instructions ( with a couple of hours of integration and darks) the image came out beautifully.
Great tutorial. I have been watching some of the tutorials for PixInsight and scratching my head a bit (including cost), but this looks a great option when just starting out.
Looks amazing! Lol I just started and my photos look nothing! Like this lol so now I’ll give this one a try or I just prolly suck hahaha. Nice video bud and thanks!
Great tutorial. I've used SiriL a few months ago and really like it but downloaded the Pixinsight Trial and will be purchasing that but I'm still going to go back to SiriL every now and then.
Heya Paul, thanks for commenting! I largely do the same thing, I still use siril occasionally, especially if I just want a quick process of some data to evaluate it! - the workflow is very quick :)
Great video mate - having used ASTAP and DSS in the past, I'm dabbling with Siril and can already see the benefits of this software; especially the photometric calibration tool. And it was soooo helpful getting the info on how you "de-green" your images. Always a scurge of OSC. I've usually done most of post in PS but there's not the astro knowledge that this software seems to have. Anyhoo thanks for taking the time to share this tutorial.
This is really nice. And concise. It took me far too much time across lots of tutorials elsewhere last Oct to come up with what you have just done in 15min! Nice to see you don't have to take it to PS /GIMP for a decent endpoint. Everything else made me believe that was the case. Thank you!
Hey thanks for taking a look! :) - I agree, the viewing of individual channels and then the rgb all on their own tab is a great help when processing! Thanks for watching
@@lukomatico I shoot right now with no astro dark(2-4 more weeks of light) and tonight i had a full moon on top of that. It's very hard for me to get something good but following your steps helped a bunch :D It's really fun to see how each night gets better tho :D
This was a great tutorial. I do have two questions though. First did you use Siril for stacking your images. Second, Siril is suppose to support processing of RAW images now. Do you know if it uses the meta data in the RAW images to remove distortion? Thanks.
Hey Jim! - I did not use siril for stacking, it was an old file I had from DSS :-) Re: metadata in raw, I assume you mean an embedded lens distortion correction? I'm not sure it can use that kind of data, as far as I know the only type of metadata it can use is the kind of data stored in .Fits headers for astrometric solutions within the program, like photometric colour calibration etc. I'm sorry I couldn't be more help there! Thanks for watching and clear skies :-)
hey, I did everything that you said in the video, but in my case the background is not getting neutralised it stays the same! any idea on how to fix? pleaseee thank you
How beautiful ❤️ May I ask why my deep sky stacker output has this red tint? I looks like your green tint all over the image but mine is all red. I don't know what's wrong. I uploaded all calibration frames: lights, darks, flats, and biases.
Thank you! - The only time I've seen a reddish output from DSS is when stacking frames from a modified DSLR and filter (or less commonly, the wrong debayer setting if using a dedicated astro cam) Does any of that sound like it could apply to your situation? Good luck! :-)
@@lukomatico ohh my camera is not astro modified. Last month's output was good but later on it gives this red tint all over the image which made it so difficult for post processing. Anyway, thank you for the idea 😊
No worries! Sounds like a setting has changed, you may need to go into DSS settings and use the 'restore default settings' function, that should work! Good luck!
Somewhere during my process, I must have forgot a step. I have a small green box that stayed on the image. How can I remove that? Thanks. Your video is super!
Hey mate! - I'm really glad you liked the video! :) regarding the box, is it the select box for one of the processes that's somehow got stuck on the image perhaps? - if so, it may be worth deselecting any boxes before saving, it's not something I've ever encountered unfortunately! I hope that helps mate! :)
@@lukomatico Ok, yes, it was from one of the processes. What I ended up doing was just closing the program and starting over again and doing it right, and carefully with every step. Thanks!!!
Great video! I'm new to astrophotography. I was using the LIVE mode on my ASIAir the other day and noticed "noisy" artifacts along the edges of my stacked images too. What was the cause of this and is this completely normal to have to crop the image after stacking?
No problem my friend! - If you have your astrometric data stored in your .fits file, or if you simply know it via plate-solves etc, then it's a superb feature! - I personally was a bit lazy with Siril though, so often times just opted for background neutralization & colour calibration instead :-D Still works well!

ive got a kind of blurry image of jupiter and its 4 big moons but with no sky/other objects to be seen in the background. how can i bring out more detail in the planet if there is no other information?

@@lukomatico thanks for the reply, i brought a bit more detail but getting the cloud belts of the planet to show just won't work. ill get a better exposure next time and try again!
Hey! sorry to hear that, if it's every file you try, then all I can suggest is make sure you are using the latest version and to try a reinstallation of the program if you are still experiencing issues :-(
I'm sorry mate but I'm the last guy to ask about Mac advice!! I literally wouldn't know where to start other than suggesting to dual-boot windows haha! Sorry man!
Hey thanks for commenting :) I'm glad it was easy to follow! - processing can become extremely complex but in many cases a simple workflow like this is enough to get a nice result! You could still do lunar and planetary astrophotography with your Dob and phone by the way! - that can be lots of fun :)
@@lukomatico yea i plan to do that in the summer i cannot wait for planetary season to start i got a few views of the planets when i got my scope (17th of november) back then the gas planets were barely in the sky after sunset and none i could see any detail but saturns rings were amazing i actually have allready done a bit of photographing on jupiter mars and saturn when they were close or even in the sky and i plan to even buy an astro cam for it.
@@lukomatico yes, I shot with my dslr and a mini refractor. Any way what do you mean by undersampling, and if I can, How can I have my stars like yours in this video. Im sorry for this questions but im a confused beginner

Hey there mate! you should just be able to open the master stacked file that DSS creates, and it will work within siril straight away usually! Hope that helps :-)
Hi Charles, thank you for commenting :) I'm afraid I failed to mention what software I used to stack the image, but I can tell you that it was done in Deepskystacker :) I hope that helps!
Hi Darrien, That seems like an odd one! - it's worth noting that Siril automatically comes on with your image in the R channel I believe when loading RGB images, and you have to click the RGB tab as you see me do a few times throughout the video to actually see the colour at that point. One other thing may be that your stacking software may not be set to debayer your images which would leave you with black and white images rather than colour - worth checking it's set to debayer them! I hope that helps, Luke

Great video ty
Glad you enjoyed it! :-)
Why does Siril load my image as black and white?
Hi Darrien,
That seems like an odd one! - it's worth noting that Siril automatically comes on with your image in the R channel I believe when loading RGB images, and you have to click the RGB tab as you see me do a few times throughout the video to actually see the colour at that point.
One other thing may be that your stacking software may not be set to debayer your images which would leave you with black and white images rather than colour - worth checking it's set to debayer them!
I hope that helps,
Luke
@@lukomatico thank you for the suggestions. I'll check.
