Description

C14 image with 0.8x Reducer and Artemis 4021 with H-alpha and blue filter, each 4x4 minutes and combined in AstroArt.

This is my first combination image, refocussing between the filters causes a difference in focal lenght that is obvious when aligning them. working at 3 meter focal lenght has its challenges.
