With constant cloudy nights thought I would go back and reprocess some Cone Nebula shots among others. I am amazed how much I have learned about processing in only a few months. Mainly from advice obtained from people at IIS. You know who you are.

Another reason is to get it up before Scott starts putting H alpha images into his red channel of normal images.

A lovely shot there Bert, Gee I wonder how that would look in Hydrogen Alpha :) I may be able to image that area between the house and a neighbours tree but it will be awfully tight.
In meantime I tweaked your shot in Photoshop, using Curves midpoint on the background to neutralise the sky background colour a bit and also this cool free plugin I was put on to

Once again a great shot, the 5DH camera is working really well.
