Description

The first thing I've been able to produce in 3 months! :-) Working out the many kinks with a new 'scope (which I'm really happy with), a balky electronic filter wheel which has since been replaced with a straightforward manual, the added complexity of LRGB processing and our lovely winter weather (solidly in the top 3 wettest years in recorded history). Always wish there was less noise, but I really like the warmth and depth that the color gives.

Description: Fully reprocessed ... not evident in the smaller image, but less noisy, better color and a little more detail.
