I can't quite belive this shot was taken in almost one hit(Ha was from a few nights ago).

That has got to be a record for me, a colour image can sometimes take me weeks waiting for good clear skies.

The image was processed as L/Ha-R/Ha-G-B.

Scope: 10" Skywatcher 250px

camera: Starlight express HX916 CCD

Off axis guided on eq6

L= 47 @ 5 mins

Ha=8 @ 20 mins bin x2

R=12 @ 5 mins

G=12 @ 5 mins

B=13 @ 5 mins

The Ha was mixed with the luminance as a 50% opacity layer set to lighten and a 70/30 (Red/Ha) mix with the red to kill the Lp (I don't use Lp filters)

and again to the result of the red/Ha mix as a 50% opacity layer set to lighten.

Mike.
