From Raw to Finished: A Siril v1.2.x Tutorial for Beginner Astrophotographers

Post your images here. I'd love to see them: tinyurl.com/yc...
This is my updated for Siril v1.2.0 beginners, start to finish tutorial on how to stack and process your astrophotography images. I'll also show you how to remove the stars from an image for better touch ups in Photoshop, and how to recombine them into a final image. Towards the end you'll also learn how to remove noise from the the photos using Topaz DeNoise.
Today I'll be working on the Crescent Nebula NGC6888 that was shot with my Celestron 8" EdgeHD using the Player One Poseidon-C dedicated astrophotography camera, through the Optolong L-Enhance filter.

I'm using the Dwarf 2 and trying to follow this tutorial - Dwarf 2 only produces Fits - lights images? how would I run this script if I have no files in the darks/flats/biases folders? (i guess Dwarf does produce Dark Frames but the dark frames are used by telescope and produces the Fits without hot pixels)

[@DeepSpaceAstro]

I'm working on a Siril Processing video for the Dwarf. Stay tuned!@@camus83489

[@camus83489]

awesome perfect thankks!!!@@DeepSpaceAstro i think lots of people using dwarfs would love a walk through.

[@mugshotmike]

Not having much success. My folders were empty when I created them, and it seems to be complaining about them and telling me to copy the pictures into each one? You didn't mention that, that I heard. Should I have copied pictures there? If not, where? Where do the fits files go? I have .NEF files from my Nikon; was I supposed to do something before selecting the process directory (such as cropping them)?

[@MentalWhiplash]

This was an absolute life-saver for a total newbie (me). 3 hours of capture of the Triangulum....completely lost myself in processing...and following this gave me a result to share. THANK YOU!!!

[@DeepSpaceAstro]

That's great to hear! Thanks!

[@paulsterman7169]

Hi. For my own benefit I took notes on the crucial steps. Please delete or modify as appropriate. Siril directions (without photoshop after color saturation) 1) Stack 2) Open stacked result file 3) Open to histogram view & use the mouse to select the cropped area and right click and choose crop (not mentioned: you can use Image processing-->geometry -->rotate&crop to free rotate). 4) Go to autostretch and use the background extractor option in autostretched mode. Use the dithering setting just to be sure. 5) Color correct: color calibration, photometric: find the DSO and select ok (make sure focal length and pixel size is correct) 6) Remove green noise, apply 7) Remove stars: star processing, starnet removal (select pre-stretch linear image, keep view in autostrech) and execute 8) Go to linear mode once stars are gone 9) Asinh transformation stretch until you start to see the details (maybe 50%, to make sure you are not clipping the blacks later) 10) Histogram transformation use and make sure not clipping the darks/shadows more than 0.1%. Start by moving the midtones to the left really far until you are okay with how the background looks. Then move the darks to the right until before you are clipping data. (not mentioned: My understanding is that steps 9 & 10 can be repeated a few times to bring out more data; I’ve done it successfully but not sure if would be the same to just do a more aggressive initial stretch). 11) Increase color saturation. Use global and if nebula try cyan. You can max it out and then do it again. 12) SAVE the image 32 bit FITS 13) Put stars back: star processing, star recomposition. Left side open the file you saved in step 12, right side open you removed star mask (starmask_result file) and adjust the stretch factor on the star layer until you are happy with the number of stars showing.

A great recap of most of the basic stuff you’ve covered these last few months Rich. 6 months ago I’d never used Siril but since then I’ve learned a lot. Whilst I use most of your tutorial, there are parts of it that I do differently but that is just preferred choice. I tend to recombine the star mask and the starless images in PS more out of habit. Thank you so much for what you’ve taught me. You’re a great presenter!

I have been shooting pro photography and videography for many years and absolutely adore Siril. All it needs is a way to stitch multiple images together and a more refined method for cleaning up luminance and color noise. But what it gives now is incredible.

[@DeepSpaceAstro]

What do you mean by stitching photos? Are you talking about placing specific photos in the color channels?

I think he means handling panoramas.

Great video! Love it and thanks for helping me with using Siril. One question: during my imaging session with my astromodded DSLR, I only took lights and darks. Is there a Siril script that can help me process with darks and lights but NOT with biases and flats? I looked into the scripts download but did not find any. Is it because it does not make sense mathematically? But how does DSS do it with just darks and lights? Thanks!

[@DeepSpaceAstro]

Thanks! Check out my video on stacking without calibration frames. kzbin.info/www/bejne/e6ewi6KuZ8mfkKM

[@johndaley9188]

I'm a newbie/beginner. I understand what Siril does but as a beginner I'm still learning the terminology. Before you cropped the image you said " see all the artifact around the edge". When I don't know what an "artifact" is your direction makes it difficult. Your tutorial is probably more for a newbie +. I did learn a lot from your video however, there are holes that I need to figure out how to fill.

[@DeepSpaceAstro]

As the images taken during a given session are aligned and stacked, you'll have artifacts around the edges. That's what were cropping out.

[@johndaley9188]

I understand that artifacts are bad, and I now know why they occur. My question is, what does it look like? Image perimeters are usually just stars. Do I look for distortion, elongation, missing, out of focus? You said it was there on the right and bottom but not so much on the left. I couldn't really tell what was wrong. Is what I just said it, distortion +, or is there something else I'm not seeing? Sorry to be annoying, just trying to learn.

[@DeepSpaceAstro]

Sorry I'm not understanding what you're asking. The artifacts around the edges are from stacking, not distortion, elongation, missing, or out of focus. Zoom in on your image and look at the edges.

[@johndaley9188]

Actually, I went to your image in your video and zoomed. I now see it. It's the result of the slight misalignment of the stacked frames on the border. All it took was you suggesting I zoom in. That's it. Thanks.

Thanks for the tutorial it really helped! Easy to follow an understand of a subject that is in no way straight forward or intuitive. I just keep rewatching your video and taking notes until I can remember the process. I did one of the orion nebula last night, shot with my sv503 80 and a Nikon D800e. I had 140 subs at 15 seconds and it took 26 minutes to process and stack. I have Ryzen 5 5600 32G ram and a AMD Radeon RX6600. Im guessing thats its because the D800e has a 36mp full frame sensor? I was very pleased with my results, thanks to your help! Cheers!

It's probably just the number of images you have. The more subs, the longer it can take. If you can take longer, but less subs, it should move faster. Thanks!

Thanks! That would be helpful to all the Mac users out there.

[@willcreek8019]

For Mac users who can't get starnet to install: The executable is starrnet++ but it does not have executable permissions. I had to open a console window and cd to the directory where I stored it and chmod 777 starnet++. The OS complained mightily about the dangers of downloading SW from an unverified source. The only options are exit and delete the file. Push Cancel. If you go to system_settings > privacy and security there should be a note at the bottom that it you tried to do this horrible thing and you can push to allow it. I had to do that three times as it complained about each of the libraries too. Maybe there was some other way to get around this, but that's what I did.

@@DeepSpaceAstro I’m a guy; of course I didn’t read the directions. 😃 I did get it working though. Thanks for your great video. I’m going to keep using Siril and abandon the trial versions of PI and APP. I also managed to get my Siril scripts working to support ASIAIR files. Surprisingly, the biggest trick was dealing with the fact that ASIAIR stacks the bias frames into a single file each. Not hard, but something I had to figure out. I quickly restacked all of my old stuff and processed better images than I got with PI or APP. “Old stuff” was 2 nights worth of data. I just got back into astrophotography after 25 years and it’s been foggy pretty much constantly since my new toys arrived.

[@starfleetau]

Rich, One step is missing in this now, which is that you need to do the image plate solver on the base image before you can do the photometric colouring (especailly if your using a DSLR)

[@DeepSpaceAstro]

Not usually. If PCC fails, yes then plate solving may get it going for you. Sometimes you can just draw a selection around an area of the image to narrow down the stars, and PCC will work.

Awesome tutorial - I just picked up a new camera after not having one for years. Interested in trying out some astrophotography, so this was great!! Subbed as well 👍

[@DeepSpaceAstro]

Thanks! Good luck and have fun!

[@michaelcole5803]

Rich, I was hoping you would update for this. Absolutely wonderful. Thank you so much.

@@DeepSpaceAstro hi, i tried to download this on my Windows 64 bit but it had a warning pop up that says "Your connection is not private". What should I do?

[@WilliamSmith-gf3nt]

I just watched this video again and I haved learned so much!!! However, I still cannot figure out why the color calibration always comes back with the failed plate solve error message. There were maybe two/three times that it worked but most of the time I get the error message that the plate solving failed and there would be no color correction. Also, when doing a wide sky view - like using SAO70288 as the center to capture the triangle of nebulaes in Cygnus - what would be entered to identify the sky area for color calibration?

[@DeepSpaceAstro]

You can try drawing a largge selection around the center of your image and then run PCC. Sometimes that works. You could also try running the plate solver first as an answer to both of your questions.

Thank you Rich, awesome tutorial. Just a suggestion and a request if it’s possible. Wouldn’t it be better to remove the stars first and then deal with the background extraction. In such case we do not have to worry whether the squares fall on top of bright stars? Any chance you can do sometime in the future a tutorial similar to this but for images taken with monochrome cameras? This will be much appreciated.

[@DeepSpaceAstro]

Background extraction should be done before stretching, and since the star removal process does that pre-stretch you're no longer linear. Maybe some day I'll put one together for mono, but I only have a OSC right now. Haven't stepped into that area yet

[@raymahl]

Amazing! Thank you so much, you really were the best help I could find on learning how to use Siril. Thank you so much, I really appreciate you!

[@DeepSpaceAstro]

Happy to help and glad you found it useful! Thanks

[@KeramRajpa]

AWESOME tutorial 🙏🙏🙏

Perfecft video, hope to see more in the future for beginners!

[@DeepSpaceAstro]

I have lots of videos for Siril if you haven't seen them yet. Thanks!

[@brianstraight1699]

Outstanding! Thank you!

You're very welcome! Thanks!

[@jtepsr]

This looks a lot easier than pixinsight. I am looking for a program with a nice understandable workflow. I am a beginner to astrophotography but I am an advanced photographer, can you provide anymore advice. Thanks

[@DeepSpaceAstro]

Yeah it is easier to learn than PixInsight. If you haven't seen them already, I have lots of other videos around Siril, beyond this beginners tutorial that should be helpful.

[@mattorsie4421]

I appreciate all the effort you've put into these videos! They have helped me a lot. I'm trying to figure out PSF registration for an entire sequence. I understand, perhaps wrongly, that you can do a PSF profile on your reference frame and that can be applied to a registration sequence. Do you know how to do that?

[@DeepSpaceAstro]

Thanks! Glad to hear they've been helpful! If I'm understanding your ask, this video may help: kzbin.info/www/bejne/oKilfYmKaKqWl9U

Hi Rich, about Starnet processing time, did you already or do you think to do in next vide a tutorial how to activate the CUDA funcionality fo nVidia graphic accelerator? Thank again for your videos Roberto

[@DeepSpaceAstro]

I haven't considered it. Maybe down the road.

[@user-um8zc2jv3p]

Thanks Rich. I'm absolutely new to all of this and started looking at 1.2.0 right away. Your numerous videos are great, but sometimes it seems a little overwhelming with all of the things you can do and in what order makes sense to do them in. Have you considered creating a flow in document form to follow so we can follow and then look up the video that goes into more detail in how to use the software's functions to do it.

[@user-um8zc2jv3p]

Rich. I also forgot to say I do not have Photoshop as it's a but expensive to subscribe to as a rank beginner. Maybe when understand photo manipulation better some day.

[@user-um8zc2jv3p]

Please forgive my spelling and grammar. Fast fingers, slow mind today it seems.

[@DeepSpaceAstro]

I haven't consider that, no. The videos outside of the start to finish one all should mention where roughly in the process they can be used. Experiment and have fun, there's no one way to do most things in the hobby.

[@GaryEasonFlightArtworks]

I'm just working through this; really helpful, thanks. At 8:46 you say , "You can see it says 'registration stacking complete'." which is indeed what I would expect it to say - but it doesn't. It says REJECTION stacking complete. What does that mean...?

[@DeepSpaceAstro]

Glad to hear it was helpful. Rejection is referring to pixel rejection. Think plane and satellite trails. Apologies for the misspeak.

[@ashandsnow1873]

Really enjoy your channel and this vid. Thank you very much for all of your hard work. Newbies like myself really benefit from this. Do you have any tutorials on post-processing the Crescent Nebula etc in Photoshop? If not, can you suggest anything/anyone? Thank you!

[@DeepSpaceAstro]

Thanks! Glad it was helpful. Outside what I show towards the end of the video, that's it, and that's also not just for the Crescent. You can use the same workflow for any object.

[@ashandsnow1873]

@@DeepSpaceAstro Thank you for the response! I am brand new to processing, so I really appreciate the advice. Thanks again.

[@user-ut5hg3gw1v]

Substitute for Adobe Photoshop? Hello Rich. I've only made it though the most basic of you processing videos and am creating some really nice photos. Thanks so very much. My Agena Astro Purchases will be made through you from now on. I have noticed the many folks, including you, no matter what processing software they use, often export to Photoshop for additional image enhancement. I have really not watched that stuff as I don't have it. At almost $300 a year in subscription fees I'd rather own my own software. Is there any substitute you can buy outright to do the things you do in Photoshop? Or does everyone just pay $300 a year because there is no substitute. Thanks. Mike.

[@DeepSpaceAstro]

Thanks so much! I really appreciate that! A lot of people use GIMP instead of PS, so that's definitely an option. Photoshop is only $10 per month, if that helps at all. www.adobe.com/creativecloud/plans.html?filter=photography&plan=individual

[@user-ut5hg3gw1v]

So you are only using the plan called : Photography (20GB) US$9.99/mo Lightroom, Lightroom Classic, Photoshop on desktop and iPad, and 20GB of cloud storage (1TB available). And not buying the full version of PS for $22.99 a month.@@DeepSpaceAstro
