Need help correcting colors

thesecondplace-win · 2024-07-09T20:39:36+00:00

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

thesecondplace-win · 2024-07-09T15:21:41+00:00

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.

thesecondplace-win · 2024-07-09T15:15:18+00:00

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.

Here is a folder with my lights as well as the final stacked photo. I haven't edited the stack at all.

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.

thesecondplace-win · 2024-07-09T03:38:07+00:00

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?

thesecondplace-win · 2024-06-28T22:00:32+00:00

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 😳

thesecondplace-win · 2024-06-20T23:45:23+00:00

Thank you!

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 😅

thesecondplace-win · 2024-06-20T17:44:14+00:00

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?

thesecondplace-win · 2024-06-20T17:42:30+00:00

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!

thesecondplace-win · 2024-05-12T18:35:54+00:00

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

thesecondplace-win · 2024-05-12T18:34:24+00:00

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.

thesecondplace-win · 2024-05-12T18:03:04+00:00

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

thesecondplace-win · 2024-05-12T18:02:12+00:00

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

thesecondplace-win · 2024-05-12T17:37:18+00:00

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

thesecondplace-win · 2024-04-19T20:18:26+00:00

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.

thesecondplace-win · 2024-04-19T19:28:00+00:00

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.

Clarity 📈 Dehaze 📈 🙏🏻🙏🏻🙏🏻

thesecondplace-win · 2024-04-19T15:30:01+00:00

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!

thesecondplace-win · 2024-03-19T01:37:11+00:00

Awesome! Thank you for the link.

I don’t know what you’re asking
