M81 4hrs of Luminance

[AstroAndy]

Hello all

So, Tue. night found me in the Ramsbury area, where I managed to get 4hrs. of luminance of M81. The subs were of varying lengths ( 66x 5min, about 10x3min 10x 1min, 1x10min, 10x 30 secs.,  70 frames. Equipment: Atik 314L cooled 2 -10 degrees,  SW200P Newtonian, EQ5 mount, guiding w/ the 50x9 finderscope and PHD2 (EQAlign for Polar drift alignment, which this time, I'm happy to say, was just a few pixels (or arc-secs.) off. Stacked in DSS, processed in PhSh CS2. This is an uncropped, full resolution image.

Regs.

I like this image.

I know it lacks colour but it is how I imagine it might appear if we were able to observe it with the naked eye - well my eyes anyway.

Thanks for sharing.

Thanks, Adrian

I hope to get more luminance, color and Ha on this object, time, weather, and Moon permitting, but I think it stands well on its own.
