Description

Used the gaps between the clouds tonight to continue testing my ASI. Still a lot to learn and also the correct spacer for the GPU is still on its way. Still have to get used to these ridiculous short subs.... with my sky 30 seconds is the limit for LUM with gain 75 ... I suppose I need to by some more hard discs ;)

Anyway, here is the lum channel quickly edited to see some results. RGB will follow tomorrow ;)
