Description

This was the first image with my AstroTech 72EDII. It started out as a test image, but I was waiting on some new parts and was blessed with a bout of good weather, so I continued to shoot.

The field flattener is a little out of spec, and so I wasn't able to get to the correct backspacing with the 2" eyepiece holder, and am waiting on a threaded connection that will shorten the distance to the flattener and allow more focuser travel. Hopefully it will solve some slight tilt in the upper left corner. I have cropped most of the issues away for this image, as well as fixed some of the distortion in GIMP.

So lots of things to continue to look into, but overall I am happy with the first attempt at this imaging scale.
