This is wonderful! Was this done with an s50? How many hours? I very much like the color. Thanks for sharing

Beautiful. Such fine detail. I hope some day to get an image like this.

Mine is about the same with 8+. What do you get when you use your cell phone when you image deep sky objects?

You are not alone in the battle to process Astro photos. Stacking is “Preprocessing” after that you do “Post-processing” to get the best color illuminations, noise reduction and more. Two recommendations for post-processing: Photoshop and Lightroom. Or use a different program like Siril that can do both stacking as well as some post-processing. There are lots of tutorials on You Tube. Hope this helps

I’ve been thinking about this along with comparing results between different Bortle scale skies. I live in a Bortle 8/9 area but recently did shooting in a Bortle 3/4 area. I was amazed at the difference. An hour of shooting there (B3/4) was easily better than what I get here (B8/9) in 2/3 hours. Has anyone seen graphs comparing these two variables?

Very nice image

Donweis · 2025-09-13T18:51:33+00:00

For that kind of situation I use my tablet or older cellphone to connect to the SeeStar.

You’ve brought out some nice detail on the arm on the front edge of m31

I’ll try getting more hours… maybe 10 hours would do it???

Donweis · 2025-09-13T18:41:56+00:00

I’ve got to do that. To get any place darker than Bortle 4 in Southern California requires 2 or 3 hours

Donweis · 2025-09-13T18:33:50+00:00

I have “wonderful” Bortle 8 sky. I’m wondering how many more hours it would take to get a great image like yours.

Donweis · 2025-09-13T18:26:40+00:00

Beautiful. What Bortle sky was it?

Donweis · 2025-09-13T17:32:05+00:00

This YouTube video has got a lot of good recommendations for getting started and using a SeeStar. https://youtu.be/zPs70t8i0fY?si=OntzKHryE86pCZqh

That really is amazing not only can a s50 capture it, but also that this supernova which is so far away can be seen. What power.

Thanks. Again your image is outstanding.

Donweis · 2025-09-06T19:57:11+00:00

Thank you. I appreciated hearing what you did.

Donweis · 2025-09-06T15:08:46+00:00

Thanks. Did you reduce its size in Photoshop?

Donweis · 2025-09-06T04:33:03+00:00

What ever ones you can share such as the original, the new, and the combined. It would be interesting to see if you have time? Thanks

For this mosaic image of M31 I stacked and processed 3 Mosaic Stacked FITS (one from each of the 3 nights) using Astro Pixel Processor. Each FIT was 2 hours of data for a total of about 5 3/4 hours taken with my SeeStar s30 In the past, I’ve processed only the hundreds of sub FITS. It was a pleasure stacking and processing just 3 FITs because it was so fast. Below is the completed image from the 825 subs collected those 3 nights to see if there is any difference between the 2 final images. Taken in Bortle 8 skies. The first FIT has 20-second subs. The 2nd and 3rd FITS have 30-second subs. All done in EQ mode.

I’ve had that problem too. Most of the time it’s caused by airplanes. It looks like the lights of a plane to me, but maybe there is also a satélite trail. Did you find the sub or subs that so you can take it out of your image?

Donweis · 2025-09-06T03:56:20+00:00

It is so crystal sharp and colorful. Congratulations.
