Graig, thank you, the sub will always look this way as it is a Raw Image with as Modified Canon 5D, the subs of any object will have that Magenta look about it.
The Stacked Raw subs turn out with a different colour cast, after being processed in Image Plus, and finally tweaked in PS2, or similar program.
Hear is a single Raw frame of the Trifid and Lagoon Neb, and one of the Helix Neb you will see what I mean.
