ASTRO: Sharpless 2-119

Last night I imaged Sharpless 2-119, which is the nebula immediately to the
"left" of NGC 7000.
As I didn't get too much detail I resized the image to 50% for a better
overview without losing detail. I used a Vixen 0.67 reducer on my Skywatcher
ED80, which unfortunately gives elongated stars near the edge of the field
even though I tried quite a lot of different distances between reducer and
camera.
I have ordered a WO "type II" 0.8 reducer, I hope this will work better.

Taken from the middle of Berlin with a Skywatcher ED80 at f/5, QHY8 camera,
Astronomik UHC filter, 11x20 minutes.

That's a whole lot of faint. I don't begin to have anything for this
size object.

I've heard good things about the WO flattener. Hope it works for you as
well as I've seen it work on other scopes. Though at this scale you
have to look for the elongation. Nor would much be lost if they were
cropped off.

Something in that image doesn't look right. It looks like one
or more subs are not registered properly. The stars "echo".

that one isn't image too often.

Nice result for your conditions

I'd never have any luck with RGB in a city!
