Imaging FSQ106N+QHY22 (1.77 arcs/pix)
Mount NEQ6 guided by a DSI Pro
Pixinsight 1.7
RGB: 16x3mins each (Baader filters)

Long time out of the hobby. Weather, family and job obligations took priority. At least I had some fun during Eastern holidays.

I have some issues with halos and the concentricity of the CCD, which I still try to solve.

It's a good image. You got a lot of the fainter stars in there. I'm not sure about the color balance, looks a little purplish to me, but every monitor is different. What color it's supposed to be is hard to say.

Thank you Hilmi and Eric. Eric on my monitor colors look ok, but I have to admit that it is uncalibrated:( , you may be right.

Hi John,

Color balance is tricky. I've been using pix insight, and it has a couple tools to get rid of gradients and automatically correct the color. I'm not sure it gets it right all the time though.

I see you are using a FSQ-106N--I've got one of those too. Nice scope. It's a cliche to say "they don't make 'em like that anymore", but actually, they really don't make them like that anymore--with the quadruplet optics, two of which are flourite. Presumably it can create a flat optical field large enough for a medium format camera. ;)
