This is my first attempt at this galaxy. Seeing was worse that my usual 3-4 arc sec. This time it was 4-5 arc sec!

The image is LRGB at 60;20;15;25. L was binned 2x2, RGB binned 3x3. Flat fielded with a new home made light box (built one for the C14 and one for the NP101 all for $85)

C14+.63 reducer+CFW8A+ST10XE, yielded an f ratio of 6.55.

Comments welcome. Thanks for looking...Ken

Nicely done Ken! I really want to take a crack at this one sometime. It is such a striking object..... very photogenic!
