I know "this is wrong" but I thought I would post it anyway.
The temperature was 23c for the entire shooting with a Canon 400d unmodified ISO 800. Scope is W/O Flt110 stacked DSS and guided with PHD.
To try to combat the efffects of the heat I took 18 x 8 min lights and then 30 x 8 min darks with bias frames and flats. Processed with Photoshop. I am tempted to trh to get the forehead and merge them but that is a new learning curve.
Looks like a great effort considering Mark. Good on ya for giving it a go!
I was daydreaming about doing a mosaic of this with the 8" reflector the other day, but with my field of view and the object's faintness its not the right equipment.
Not a bad result Mark. You maybe able to raise the blue channel black point to remove the overall blue cast or try a contrast curve on the blue channel only. The Witch isn't easy to nail. You've done a good job.
