- In this video, we'll explore the new StarNet integration within Siril. StarNet is a powerful tool for image segmentation, which can separate the stars from the background in astrophotography images. This allows for more accurate processing and enhancement of the overall image quality. I'll walk you through how to use the StarNet integration within Siril, step-by-step, and provide tips and tricks for getting the best results.

By far the best explanation of starnet in Siril I have found and explained in a way that even I could understand. Thanks so much. You have just earned yourself a new subscriber
Thanks! Glad it helped!
This was an excellent explainer. Thank you for taking the time to explain it. I used it recently to walk through my own image and am grateful!
You're very welcome, and thank you!
I just heard back from the devs about how the recomposition tool closes when clicking Apply, and they confirmed it is a bug. So it'll be fixed in a future version, but may take some time to implement. Also, the bug mentioned in this video has been corrected in 1.2.0 beta2.
Omg!! A game changer!!! Already used this video to learn how to use this!! Thank you. Incredible video as usual.
Thanks!
Another great tutorial Rich! Love the way you show the bugs and what happens if you don't do things right, really helps in the 'real world' scenarios. Typical this came out just after I learned from your previous video on stacking comets using Pysiril, was a lot of work but enjoyable and I ended up with a great comet image without streaks for the first time! 😀
Hey thanks so much Mike! Yep it figures this kinda sunsets my other videos using Starnet! Oh well, just means I'll have to make more eventually. lol Glad to heat you got good results with your comet!
You’ve got me addicted to Siril with your tutorials which are very good and easy to follow. I managed to get the new Starnet tool working and whilst I think it’s ok I still prefer to take the 2 files back into Photoshop for further processing, particularly the use of Star Xterminator which is an awesome tool for noise reduction. I’ve played around with NR in Siril and I’m not particularly impressed with it ….. of course it may be my ignorance! Thanks for sharing 🤝
Haha! Thanks! Yeah I don't think there's much out there that can compete with NoiseXterminator.
Super useful and easy to follow. Thank you!
Thanks! Glad it was helpful!
Configuring Starnet has changed slightly since this video was released. You now have to select the starnet++.exe file instead of the folder in Siril's Preferences.
It took me hours to work out there’s a bug in Siril with star removal, you explained it perfectly on the workaround
Pretty good channel on Siril mate, I’m using your script for the Hubble pallet on osc images, bloody awesome 👏
Thanks so much!
I learned a lot from this video. One of the best take aways was how to take the starless image out to process with Photoshop or Affinity Photo 2 (in my case) and then bring it back in and create a fits file for the star recomposition.
Glad it was helpful!
Just wanted to say ty for this, been trying to find a way to do this without layers in gimp. Im very noob to this, but this video made my first captures much much better
Glad to hear that! Thanks!
This is a great addition to Siril and your video is excellent, thanks for putting this together.
I also want to caution anyone using this on another bug I just found. In the evening I left it running on a sequence of 253 images, when I got up in the morning it was on image 157 and suddenly started erroring out with Siril and starnet both reporting that it could not find the .../process directory (this on OSX). I poked around and could find nothing wrong so I exited Siril and restarted.
This seemed like an easy issue to solve w/o losing the 8 or 9 hours of work that had already been done. I simply went into the sequence and disabled the first 156 images leaving the remainder enabled. I then started Starnet back up to process the enabled images in the sequence.
WARNING WARNING Will Robinson! (Showing my age). Apparently the starnet processing explicitly deletes all of the starless* files when it starts and so I lost the overnight run.
User beware.
Thank you, and thanks for reporting your findings!
Great videos, thank you! Recently started using Siril as my main stacking and editing sw. Now I am wondering in which order Siril image processing activities should be done to get optimal result. Crop, photometric color calibration, background extraction, removing green noise, noise removal, starnet processing and stretching the image.
Besides the functions where it's recommended to be still in a linear state, I think it's up to you what you feel works best. For me I usually do crop, background extraction, photometric color calibration, removing green noise (if needed), noise removal, remove the stars, stretch, touch-ups in Photoshop, and then back in Siril to recompose the stars for the final image. Sometimes I skip the noise reduction and do that with Topaz DeNoise in PS.
12.03 beta version 2 was released in which many problems were fixed, now it works without crutches.
Yep. Good news!
Thanks for pointing out the windows bug. I thought I had done something wrong.
Yeah lots of people thought the same. The joys of beta software. 😁
I really like your videos. You get strait to the point and dont dilly dally. Also the way you point out potential problems both in setup and use is most helpful. I have been using Siril for about 3 years and they have really upped the game with the new version.
Thanks so much!
@@DeepSpaceAstro I'm looking forward to your video on GHS. I've been using it Pixinsight and have a pretty good handle on it , but its always good to get more input. It is an incredible tool.
Just found your channel and I'm really enjoying it. One question about star removal and background extraction. Do you think it will affect the BE algorithm if I remove all the stars first and then use BE with the auto sample generation? The first image I'm trying with Siril is very star rich. It would be much easier to generate the samples if there were no stars present.
You could yes but you may find that you would then need to run it on the starmask as well. Another option would be to manually place the sample points, you don't need that many when using RBF. In the end, it doesn't hurt to experiment.
@@DeepSpaceAstro Ah, good point. I didn't think about the mask.
More great stuff... I'm trying to learn Siril by using Seestar subs (with the Seestar script). From what I gather, any Siril image you want to work in Photoshop (CS6) must be saved as a tif file (like to your desktop). Then, after the PS tweak, let Siril try to open that tif file and and it will be converted back to a fit file so you can add your worked stars back in? Thanks for your thoughts or corrections, Michael
When you save it out as a .tif, make sure it's 16bit. Open in in PS and save when you're done. Open the .tif in Siril, and save it as a 32bit .fit. then you can use that .fit for recomposition.
Very happy to come across your tutorials. Excellent work. I use Siril and Photoshop.
Assuming I’m doing star removal from the Star Processing menu while linear…
Would you do Deconvolution prior to the star removal? I think that’s necessary because SiriL is using the stars to create the Deconvolution math on the rest of the image, correct?
I also wonder whether to perform some star reduction with the starmask fit, and if so, how so. I just did some by the stretching of the mask image in Recomposition, putting SP HP and BP at .002/.90/.05 then allowing a large stretch.
My challenge is a 2855mm native fl with 3.76n on the ASI2600 sensor. I use an 0.62 reducer and Bin 2x2 in the camera but tight stars has been a challenge so far.
Thanks! Yes decon first then star removal. That's how I usually reduce the stars, by stretching them in with the recomp. However, this may help with a final image as well. th-cam.com/video/Na6GzKozpCI/w-d-xo.html
@@DeepSpaceAstro Yes I installed that script as well. To test my understanding, one could run that script after all processing was done as a final tweaker process- perhaps modifying the 0.20 given that I would have already done my Star Processing and separate background stretches, and already used the Recomposition stretch to limit the amount of stars brought back in. But it could do a ‘little more’ given that Recomposition did flatten the two files back into one.
Yep that's correct.
Really enjoying your videos! I am trying to learn Siril but realize there is as much art as science. What's the clicking noise?
Thanks! What clicking noise?
@@DeepSpaceAstro at 2 , 5, 7 and 10 seconds. Ok now I see it's synced to the links appearing on screen.
Would you be able to create a tutorial for processing comets with the starnet tool? I would like to process the files I took a months or so ago since I am not pleased with the results I got with the previous process I used (stack on siril, remove stars with starnet and combine star+starless files with gimp)
I have a couple of comet stacking videos that may help. They're not using the integrated Starnet that was introduced in v1.2.0, since it was recorded before then, but they should be helpful.
pretty cool features! who knows 😁 Siril may become as cool as Pixinsight for a huge portion of astrophotographers who don't have 300 $ + 100 + 100 ....
if they can Sus the deconvolution to say 50-60% of blur exterminator.... game over ...
Yep. I think they're close to being what GIMP is to Photoshop.
@@DeepSpaceAstro from what I gather the only things that are amiss are deconvolution sort of thing tithe blur exterminator spec and HDR multi scale transformation which should help with the likes of M42 and such bright objects...
hopefully more goodies on the way 😉
BlurXterminator is not available for Photoshop. Why not implement it in Siril?
@@indysbike3014 That's a question for the dev of BlurXterminator.
I bought you a coffee and am a member now. once again, I'm having a problem with installing starnet on siril, I have v1.2.3 . i followed the instructions on your video but can't get it loaded . I have no idea what I'm doing wrong ?. I have tried different ways nothing seems to work . I love your channel and you do great videos! I need help rich
@kengarris1046 Thanks and welcome! I need as much details as you can give. What are you seeing? Error messages etc. What OS?
@@DeepSpaceAstro windows 11. I'm getting an error message "no valid starnet executable found in the configured starnet installation directory, check your starnet installation and siril configuration" when I downloaded starnet and unzipped it the only thing that would is the starnet++ exe. I could not get starnetv2cli_win to load into siril .when I click to open it the file displays all the sub files and doesn't load into siril . as you can probably tell I'm not real computer Savy please help!
Very good tutorial, I learn a lot with all your vidéos. Pity you speak too fast for a a not english very well speaking frenchy 😂 but with replays and subtitles I Can ! Thanks
Thank you! Sorry about the fast speaking
I tried to use the Siril beta plus Starnet 2 to process C2022E3 comet data in a manner somewhat to how you did it with the 1.0.6 version. My approach was like this:
- preprocess the lights (flat, bias integration) to get the pp_lights_.seq
- background extraction on that sequence
- Starnet2 to remove the stars from the sequence
- Create a new sequence with the new starless_* .fits files
- Comet register this last sequence
That does not work because apparently the fits header information is not maintained across the Starnet process and this is required so that the comet registration can get the internal timestamp and thereby properly interpolate the comet position. Too bad as I think this would be a handy way to do it. Maintaining the fits meta data across the process is possible (either by writing it as meta data to the tiff or via cut-n-paste transfer from fits to fits) so maybe someday that will happen. ;). Meanwhile I had to back up and use the register & export sequence shenanigans you showed in your earlier video. ;)
Thanks for the method!
Interesting because they deprecated the Python script I used in the video saying this was the replacement. When you used Starnet to remove the stars from the sequence, was it from the registered sequence? I haven't tried running through the process myself yet to see how it changes using the integration.
@@DeepSpaceAstro Yes, it took me a while to realize that two registrations are necessary to process a comet: one to align the stars (keeps the comet from moving around due to "dithering") and then a second on that registered sequence using the comet align registration. After doing the first (global star align) I ran these through starnet (not saving the starmask .. see below) and then comet-aligned the result.
I did a cheat for the star field. Given that the comet is moving, I went back and took about 100 shots of just the stars after the comet had moved out. I was lucky to get a break in the clouds for two nights in a row, on the first I shot the comet, saved the sequence I used for that in N.I.N.A., and then reused that same sequence the second night to get just the stars. I used Siril to process the starfield, copied over my reference pp_light from the Siril comet session to the starfield session, created a sequence that combined all of the starfield pp_light FITs files with that one from the comet session, designated that one as the reference, and did a registration. I then disabled that one FITs file when I did the stacking.
I used the new recombine function in Siril to put the comet and starfields together. This requires a bit of Photoshop trickery to match the cropped down image of the comet with the size of the starfield. The end result was not too bad.
Btw: I experimented with the Desaturate and Full Resynthesis. The later is cool but a little to aggressive for my taste, tends to look artificial esp. with the deep black background that results.
Hello, beautiful job. I installed everything on windows, but I can't install on Mac. There is something that needs to be done but I can't. Do you have any help for me? Thank you, Alfredo
I don't run Mac, but I may be able to help if you give me more information. What are you seeing? Are their any errors, etc.?
@@DeepSpaceAstro Hi. I proceed regularly, I extract the folder, but in SIRIL the program responds: ERROR. You don’t have permission to execute this file …….
@@alfredospagnoletti6747 Make sure you're following the instructions from the Siril manual for Mac. Sorry I can't be much more help since I run Windows. siril.readthedocs.io/en/stable/installation/macos.html#installation-of-our-app
Those new features of Siril along with your excellent video tutorials have elevated my astro photos processing to a much better level. Thanks!
I have a question about mapping Starnet++ CLI within Siril. I could figure it out just fine on Windows 10 but for the life of me cannot get it to work on W11. It never gets me the “Select Folder” option just an “Open” option which leads to another folder until there is nothing else to open. That is in the beta 2 version. What am I doing wrong?
I'm on Win11 and it works. You went to Preferences and Miscellaneous, clicked the folder icon, browsed to the StartNet CLI folder, and selected the starnet++.exe file?
@@DeepSpaceAstro Yes I did, but still the Execute bottom remained grayed out.
I don't follow? What execute button?
@@DeepSpaceAstro The one at the StarNet Star Removal menu as seen at 8:12.
Not sure why. If you've configured it in the preferences and you are using the command line version of Starnet (not the GUI version), then it should work.
Is this fixed in Beta 2? I hope so. Seems every time I follow one of your videos to do something I'm not seeing what you are displaying in going through the process. I downloaded the .bat file for launch of Siril. I can't go any further since I don't get the RUN ANYWAY box that you are getting.
Yes you no longer need the .bat file in beta-2
What is total exposure time for this image? I’m working on a Cygnus image now and I’m at 4.5 hr and have about half or less of the detail.
This was 40x240"
@@DeepSpaceAstro would you mind if I ask what your set up was. I’m using a Askar300FRA pro with a ASI2400. I had roughly 40x300”
@@mr.mushroom1888 Not at all. This was last year and I used my Redcat51, and the Canon M50 Mark II. I think I also used the L-Enhance filter and I'm under Bortle 4-5 skies
Is the starnet website still present? It is not loading.
Should be. I've seen it go down in the past for whatever reason. It always comes back eventually.
I am Linux user and I didn't find hot to integrate Starnet into Siril. I choose valid directory and executable, but Siril don't see StarNet at all. Have no idea where to dig to make it work. Though I don't really need StarNet, but I want to find out how to make all work together.
What's the message from Siril?
@@DeepSpaceAstro Something like "no connection with StarNet executables". When I try to run it in terminal it says "Permission denied". Perhaps I should place StarNet folder somewhere into Siril directory.
I'd try setting permissions on the directory where StarNet resides.
I have the latest version of siril, 1.2.0-rc1 and they took down the command line from their website for starnet .I entered it manually but could not get it to load.can you send me the link PLEASE. thanks in advance Ken

The starnet++.exe? Sorry, I need more details on what you're doing.
HI Rich sorry to bug you . I sent a response to your last message for more detail but I don't see my reply in the comment section . did you receive it? ken

The onlt thing I can get to load is the starnet++ file. Do I need to go to the scripts fill in preferences to put something in there to make this work .
It's changed a bit since I put that video out. You need to select the starnet++.exe file in the preferences, not the folder.
@@DeepSpaceAstro ok did that still not working same error message. could it be my working directory I have on but haven't set it up with the celebration files yet.
I'm a terrible typist
Why are you promoting people to use incomplete and buggy free software that the majority of users won’t be able to get to work?? Stop.
Umm that's the whole idea of these videos. To help others understand and be able to use the software. It's far from being incomplete and buggy, but if you're having issues I kindly invite you to watch my series. ;-)
You're obviously NOT an astrophotographer!
I meant Phil Segre, not you Rich! Keep up the great work. I looked at Siril 2 years ago and found it incomprehensible. Now, with your youtube channel, it has real potential , especially glad to see the live stack features, as i consider myself more of an EAA guy right now.
Oh I know. lol Glad you found the channel helpful!
