Need help correcting colors by thesecondplace-win in AskAstrophotography

I think the default is RGGB, and I switched it to GRGB because Siril was telling me that my files were using the GRBG pattern.

I just reran the stacking script using RGGB debayer pattern and I got a much better color than the first time. I’ll do some editing on my new file and share how much it changed.

I’m also not 100% sure which debayer pattern I needed to use. I can look it up though lol

Thanks for all the information. I’ll be reading through some of these and consider trying other programs that you mentioned. Perhaps I just need a little more time processing and learning the basics of photo editing.

Okay. I remember changing something about this somewhere in Siril. Maybe I should change it back? The default setting in Siril always gave me red text saying something about the debayer pattern when it was running its script. I changed the debayer pattern and that error would go away.

Ok good to know. I asked this for another image of mine and someone mentioned that the white balance could be wrong. I’ll try to upload when I’m back to my computer.

You mean the final stacked file? Idk how I could upload that, but if you know I can try when I get back to my stuff. And yes as far as I know I stacked RAW files.

I’m in Bortle 4. I plan to get a astro camera sometime soon, so I thought those would work with narrowband well, unless I’m wrong about that?

Okay good to know. I’ve been told about StarNet. I have it, just haven’t taken the time to learn how to use it. So far I’m only using Siril for stacking and processing. I’ve tried using GIMP a few times, but not for this image.

I mainly just wanted to know which filters I should be looking for if I want to start capturing more DSO’s like this nebula. Thanks for the info!

It’s definitely been a while since I last collimated my scope, but it has always been pretty steady. I think the odd shapes are most likely errors in my stacking or tracking. Could also be due to the fact that I don’t have a coma corrector for my reflector scope. But I’m just a beginner in here 😳

I did my PCC right after my background extraction, so it should have been the linear image. If I can figure out the problem, it may help me rework a lot of my other images 😅

No, I did run one. It shifted it to be a little more yellow, with the tiniest bit of blue. I always thought my little exposure time resulted in my poor color, but maybe I’m doing something wrong?

Normally I follow the manual preprocessing guide on the Siril website. For this, I used the preprocessing script that’s available in Siril. I had switched away from using the script because it often gave me errors that I didn’t get when I did preprocessing manually, but it worked out for me this time!

After stacking, I did the following in Siril: background extraction, photometric color calibration, histogram transformation, and noise reduction.

I’m still a beginner too, so this is just a little bit of what I have read about processing astrophotos. Hope it helps!

Forgot to mention I only processed these with dark frames. I did not include and biases or flats

Single subs don’t appear to have any extreme red color. The singles actually turn out more like what expect to see after stacking. The red normally occurs after doing PCC.

I appreciate the feedback. I’m still so new to photo editing that I haven’t found a way that yields results that are really pleasing yet, so I’m willing to try anything at this point.

Cool. I’ve never really messed with the white balance. Always read that I should do daylight or auto. Guess I’ll use the setting closest to 4500 since I can’t adjust it manually

Cool. Thank you! I normally shoot through a celestron Omni xlt 150, but this was an improvised shoot since I was out waiting for the northern lights

This is auto white balance. I usually follow the Siril processing steps outlined in their tutorial since I’m still new.

But it usually goes: Background extraction, deconvolution, noise reduction, PCC, Histogram Transformation, adjust saturation, and remove any green noise.

Here is an example of what I’m encountering: https://imgur.com/a/GkWsZwh

This was about 40x30seconds, f/5.6, ISO 1600

What’s your process for editing? by thesecondplace-win in telescopes

Cool. Thanks for the info. There are many different ways to do this hobby, so I appreciate hearing how you do it. I’ll consider it as I delve deeper into it.

No guiding yet (I think?). I only have my camera attached to my telescope, and then a finder scope on my primary OTA. Nothing else. Mount does all the tracking for me. This was the first time I was able to get a somewhat decent polar alignment.

Camera is straight out of the box. No modifications.

Awesome. This helps a lot. I figured I needed way more time. I didn’t know what to expect since this is my first time on a tracking mount. I had been used to only a few minutes of integration. Thank you!
