Dumbbell Nebula (with Smart Histogram Brain used)
Posted: Thu Jul 30, 2020 1:07 pm
M27 Dumbbell Nebula / The Netherlands in Bortle 8
Finally a clear night
Not perfect but good enough.
Here my first capture of the Dumbbell Nebula and also first use of the Optolong L-Pro multiband filter.

Also for the first time: I used the Smart Histogram Brain settings
The camera makes the difference: with the Zwo ASI385MC it just wouldn't work but with the ASI294MC Pro it does. Bigger FOV, gathering more light so stacking is no problem.
