Description

A beautiful clear evening last night and a boneheaded mistake that threw a monkey wrench into my imaging session. When I upgraded from my ASI533MC to the ASI294MM I inadvertently removed a spacer that was supposed to be part of the field flattener. Needless to say, I ended up cropping this extensively but even this was not enough to hide the evidence of elongated stars.

Aside from the back spacing issue, the session was still worthwhile for learning more about mono processing. I shot the stars in RGB and then shot the target in SHO. Stars were removed from the SHO image and then combined with the RGB stars. Still a long way to go but hopefully the clouds will clear tonight so I can have a do over with 55mm of back space!
