The Iris Nebula / NGC 7023 / The Netherlands in Bortle 8

A work in progress, busy with gathering more data. But over here just patches of clear skies: one hour and then clouds, each night :cry:
But enough data now to share this. And my first reflective nebula.
Also now doing 180 seconds exposures at 2030 FL without guiding. That mount really rocks!

Meade LX65 8" f/10 ACF OTA
Ioptron CEM25EC mount (no guiding)
Baader Neodymium Skyglow filter
Zwo ASI294MC Pro camera

Captured with SharpCap @ -10 degrees Celcius / Offset 30 / White balance 50/50
40 x 120 sec / Gain 121
24 x 180 sec / Gain 121

Stacked in DeepSkyStacker with blacks + flats + dark flats

Processed in PS: Levels, Curves, Shadows/Highlights, noise reduction, cropped, scaled down

Okay, this is no WIP but finished capture. But I'll post it here :)
In the end I used 35 x 120sec + 40 x 180 sec. But light pollution started to creep in :(
But very happy with the result :D
Full version is 3890px.

Thanks Nick!
Well, even looking forward to short nights without clouds :p
Prediction for next 2 or 3 nights are good ... so going to do my first Dumbbell capture :)
