52 x 5 min ISO800 lights (4.3hrs). 13 Darks (from a previous night) & 10 flats (my 1st attempt at flats, twilight flats). ED80 guided with ZS70ED on G11/gemini, canon 450D.

Moon light kinda spoiled 1/2 the exposures but I kept them. I couldn't do new darks as my camera battery was "kaput"!

I've designed & built a 12V to 8V PSU for the 450D with under/over voltage protection but I'm not happy with it (the linear regulator) & have new generation linear regulators with current sense & shutdown protection ..on the way!

I counted 18 other galaxy's in the frame.

Anyway...for what it's worth.
4.3 hours of exposures. Difficult is an understatement. The tracking is superb . Is that sort of brown color ihn the background the result of the moons light pollution?
