NGC 3199 is a fascinating object in itself-a moving (?) Wolf Rayet star 18 which is producing a distorted bubble or ring in the surrounding uniform interstellar medium, sculpting fantastic shapes, the brightest part of which I like to think of as the smile nebula
In this 2.38 x 1.58 degree field we can also see NGC 3247 in the top of the frame -which google says is an open cluster- Hartung's actually says John Herschel made an error in describing this object as a "decidedly nebulous group".

well it certainly looks nebulous to me.
There is also a another small but relatively bright nebulous patch in the bottom right near NGC 3199 which I am unable to identify, and of course the whole region appears suffused with nebulosity.
Its all quite fascinating and relatively less imaged region of the sky
boring details:
90 minutes of exposure-15 minute sub frames (actually shot two hours but found a trial 30 min sub was too ambitious for my system and had to toss it)
Camera: QHY 8
Filter: Baader 7 nm H Alpha
Scope: ED80
Mount: CG5 Autoguided (Orion DSCI/PHD Guiding)
Location: Winston Hills -Suburban Sydney
more noise then I like but I stretched the image to reveal more of the extensive nebulosity

thanks for looking
in particular any tips on managing noise and improving processing would be appreciated
