Being not familiar with Dedicated CCD's I was just wondering why their is 6 different exposure times...I see 4 reguarly such as HA & RGB so how does the 6 work and what do they stand for.
Hi Tony

I use Red (R) Green(G) and Blue (B) filters as well as a Halpha (Ha) and of course the whole visible spectrum with the Luminance (L) filter that only blocks infra red and UV. For this image I combined the Luminance , Halpha and Red exposures to form the Luminance (LHaR). I then added this resultant image to the RGB combo to produce the final "LRGB" result :-)
