ngc 7793 - A ROAD LESS TRAVELLED

Goaded into activity by Forum friends, I turned my little 8" Newt and new QHY8 onto NGC 7793 tonight to see what the limits were. Here are some of the built-in limits - no Flats. My new LightBox is in the post. So what we have is 6 x 20 minute light subs with a QHY8 at Gain1; Offset 110 with off-axis guiding and PHD - all Remote Desktopp'd back to the house.
I wanted to see how far I could push guiding and what the limits of resolution were for the GSo newtonian.
As far as processing goes, it is just a succession of Levels and Curves repeated several times to bring out detail.
Anyway. Here is a crop from the image - crop to avoid the obvious consequences of not having any flats to apply. But this time next week will be a different story - I hope.
