M81

[alan4908]

This is my first attempt at M81 with my new imaging set up (SW Esprit 150 on a 10micron GM1000HPS). The combination of the scope and the camera (Trius 814) yields 0.7 arc seconds per pixel which seems to work well on this object.

The following is an LRGB image, processed in PI and PS and represents just over 12 hours integration time.   

I do like the colour of the galaxy arms and I was impressed with the details of the Ha regions, given that I did not use an Ha filter.
