Hi,

I've been planning to do this for a while, but it was a real dog to get rid of the gradient between the two images. The image with NGC 5090 at centre was taken in less than ideal conditions.

8” F/4 astrograph , baader type coma corrector,. HEQ Pro 5 mount, orion mini guider.
Camera.
Unmodded Cannon 1100D. Cooler box.

2 x 11 x 8 minute subs ISO 800 , darks, flats and bias frames applied.
Stacked in Deep Sky Stacker .Processed in Photoshop 7 and Olympus background subtraction tool kit.

Cheers,

Justin.
