First time out with my Zenithstar 103. Great scope and the CEM25p handles it no problem. Over 2 nights I captured 4.5 hours of the Iris Nebula and lost some subs due to airplane streaks and clouds.
Here is my poor attempt at processing 4 hours of data in Photoshop. 83 subs, 3 minutes each (gain 50 offset 10) at -10deg. 30 each dark/flat/bias.
I feel like I should see a lot more dust. I know I shouldn't compare but Trevor on AstroBackyard was able to pull out brown dust against the black background in a 44 minute stack using a similar scope and similar OSC camera in similar light pollution.
I tried a run with the "screen mask invert" technique but didn't have much success.
If anyone wants to give the data a try, here is the link to the stack out of DSS (with changes embedded but not applied):
