Don't you just love the way you can plop a Seestar down and in a few minutes have a very nice snapshot of a DSO? Sometimes it just seems too easy
Nice picture I couldn’t get that green colour

It's nice to see what different smart scopes do on the same object

This was a target I wanted to try for a while - it’s really beautiful - I was hoping for a more green colour if I’m being honest but viewing wasn’t that great, about 70% but it was good enough for a try and what I got I am really happy with. This scopes potential never ceases to amaze me!

This is direct from my Seestar S50. It is just over 8 minutes of 10 second exposures with the filter, taken less than 50 miles from Chicago. The only processing was resizing to fit the forum requirements.

The only way to really do a good comparison between scopes for a target is to use all the scopes in the same night at the same place for the same amount of integration time and processed the same. Everything else is just anecdotal shots without knowing the variables. Here is an anecdotal image of the Dumbbell nebula with the Origin
M27 (dumbbell nebula) data collected with the Origin back on 07/15/2024.
2 hour integration using Celestron nebula filter. Bortle 7. Post-processed using features form the following programs:
Siril - photometric color calibration
GraXpert - background extraction, deconvolution (both stars and image), denoise
Affinity Photo - levels stretch, separate stars from nebula, curves, more background extraction, more denoise
- used StarXterminator and Topaz denoise
- cropped
