Thanks guys for your comments ... and YES I'm sure it is addictive. I feel like I have to get outside and redo all my imaging because I threw out a lot of frames from past sessions as I couldn't do any stacking of full frame images from my 350D with Registax and so I only kept the ones that I processed as single shots.
Never mind ... as soon as we get some decent clear skies here ( within the next few days according to the TV ) I'll get out back and see what I can come up with.
Cheers All !
