Look fwd. to seeing the colour version.

Thanks John. I haven't reached for it until now as my FLI cameras do a good job. But a small sensor with high QE would be just ideal for galaxy imaging with this rig.
The ASI6200 looks like a game changer as well.
Amp glow dark calibrated out easily and there was actually very little in the 10 minute exposures.
I finally got all the softwares updated (my observatory computer is a Windows 7 jobbie). Latest softwares insist on the latest Ascom, Service Pack 1 for Windows 7, a late version of .Net Framework etc etc.
Its taken a day to get it all sorted but now its working in Sky X where my autoguider and filter wheel are. So now its business as usual with the new camera.
I'll have to try this short exposure lots of stacking approach at some point.
Is that still the go or are imagers going for longer exposures now?
I don't see its any different to a normal CCD in that regard. Short exposures though may be sharper due to less guiding errors and seeing effects.
Greg.
