Description

Test on M51 Whirlpool with BRC 250. Adjusted primary collimation to fix on-axis collimation issues. It appeared to fix the problem I was having. Followed the Deep Sky Instruments Collimation procedures, was easy to follow!

Also I did not take flats on this test image so please excuse the artifact on the lower left. It was a piece of lint or hair on the CMOS sensor, I later discovered.
