Well, it's technically not Luminance per se, more shot through the CLS filter, but essentially the same thing.
These are 30 second subs, approximately 360 of them.(About 3 hours of data).
Camera was at Unity gain.
Shot through my Sigma 150-500mm lens at 500mm (f6?)
Some gentle sharpening and contrast enhancement and noise reduction, all courtesy of Astra Image.
Experiment (when the clouds disappear): drop the gain to its lowest and see how far I can push the subs. I tried 3 minute subs through the red channel the other night at Unity gain. It was a grey screen with a few white dots. Not good at all.
The only thing is the 4 hours my laptop took to process the 360 images today in DSS. Hopefully my i7 16GB RAM tower in the office will do it a bit quicker!
Anyway, thanks for looking and C&C welcomed.
