Description

Tested my new collimation with an screwable collimation laser screwed to the GPU coma corrector. Seems that i am finally able to reproduce a quite good collimation. Decided to go for a little M101 to test the collimation.

Had to deal with hard gradients in the stacked image as the raising moon (+50%) was brighter than i thought^^
