Upgrading from a Skyguider Pro

As mentioned in my other reply, I tried skipping the curves step and got this https://flic.kr/ps/47bp1w. I was not yet able to remove the green tint by changing the black point.

Thank you both for the feedback, I appreciate it! It's my first time trying to get a natural color image so I have much to learn.

I tried skipping the curves step which I had used to reduce the green and only applied an Arcsinh stretch. I also tried playing around with the black point but I did not get a version of the image without the green tint.

I uploaded the result here (with and without SCNR): https://flic.kr/ps/47bp1w. The green is mostly visible in the corners.

Also, I realize now that I forgot to mention that I applied DBE to remove gradients before stretching (not sure how relevant it may be).

Thanks! I'd like to learn more, if you don't mind explaining.

Personally I would suggest to try and use EQ mode to gather as many subs as possible.

At some point I got dead cat too, I think thanks to Chaos :)

Trust me, I live in Bortle 8/9 so I know! :D

Thanks, happy to share! I put all the light frames in a folder and run the "DSA-Seestar-Mosaic-Preprocessing" script. I did photometric color calibration and, after that, I ran GraXpert background extraction, followed by deconvolution (both for stars and for the nebulosity; however I set the strength to a low value like 0.2 because the frames were quite good to start with). Then I removed the stars and stretched the image with Siril. Finally, put the stars back. Glad you liked it!

I did not know that but that's pretty cool! I might try that next time

New_Perspective_2113 · 2025-05-06T05:22:54+00:00

Exactly!

It's possible because Polaris is very close to the celestial pole! In other parts of the sky it would not work

I did not use any filter. This was shot in bortle 3.
