Default ASTRO: M51, M81 and M82

Hi to the group,

With some clear skies here in Manchester UK I managed to get some reasonable
galaxy images. Both images were taken using a Skywatcher ED80 and a
Starlight Xpress SXV-H9 CCD camera. I used my Celestron Ultima 9.25 and a
Philips Toucam Pro webcam as the guide camera with the excellent PHD Guiding
software package. It was a bit too windy to image with the U9.25 so they
switched roles.

Each image is a stack of 30x5 minute exposures at 1x1 binning. I ran out of
time to get RGB frames as I had to go to bed - work next day !!!!
Processing was done using AstroArt 4 and Photoshop CS. No dark frames were
used, but each of the sub-images was corrected using a master flat frame
made from 25x1 second images, an illuminated white wall and a T-shirt :-)

Regards
David Cash
