Description

This is a combination of a f 2.8 Sharpstar astrograph 420 mm focal length and a Lacerta APO with 430 mm focal length for the stars. The stars were terrible in the channels with the Sharpstar. Therefore I couldn't replace the stars in the lum channel properly an had to dump 5.4 hours of luminance.
The rest was a hard fight agains star artefacts.
Here is the result.
Hope, it's not too bad.

Christian
