Description

M39 is an open cluster in Cygnus, approx. 1000 light years from Earth. Its age is approximated between 250-300 million years. 

This is first light for my carry-on capable imaging setup. Some tilt remains to be fixed, which is the reason for the crop. I'm very pleased with the star rendition: I see almost no CA, and the spots are far smaller than in the other portable scopes I tried.

Processing on this is only a (heavy) background extraction, photometric color calibration and stretch with GHS. No sharpening/deconvolution, noise reduction.
