M27 Outer Shells

[Roy Foreman]

I've had several attempts at trying to record the outer shells of M27 this year, and posted a couple of them here, but never really been completely happy with the results.

This is my best effort to date.  I'm sure there is still room for further improvement, but I'm reasonably happy with it for now.

As always the lack of decent clear skies means I have to gather as much data as I can in the shortest possible time, so image quality suffers. Not much we can do about the weather.

Vital stats as follows :-

Celestron 8" F/10 Edge HD

ZWO ASI 6200 MC Pro

SW CQ350 mount

IDAS NB! Tri Band Filter

34 x 120s at gain 400

Stacked in Affinity Photo and processed in Photoshop.

SQM 20.49

Thanks for looking.
