M81 with C14

I had some time today to do a preliminary processing on an M81 image I took under light-polluted conditions in my front yard. Equipment was the new C14, a Finger Lakes IMG 42-40 camera (2048x2048, 13.5-micron pixels), Paramount ME. 25 5-minute images binned 2x2 in luminance, color added with FCT-150 and CM-10ME camera.

With a total of 125 minutes of exposure, the result overcomes the limitations of light pollution in many respects. The worst problem I had to deal with was the lack of a flat field - I only had the camera three days and never got a flat to cover this filter combination. With light pollution, good flats are essential. I did some quick adjustments manually in Photoshop, but the image really deserves a more careful manual flatting for optimal results. That will have to wait until I have the time!

Fantastic Image Ron, I am so used to seeing this and M82 as a wide field shot, I was wondering what it looked like up close. Your giving those RC scope owners a moment of pause. Do you have this mount permimently setup or are you portable?
