Given you have STXL11002 and STXL6303, it would be interesting to see how they compare in Ha (you know, QE diff, NABG vs ABG etc). As in end result pic with similar total imaging time.
Thanks Fred. They were 15 minute subs. The 6303 CCD is twice as sensitive as the 11002 at Ha. However the 11002 is slightly better (50% vs 45% at OIII. I plan to do some more infrared with the 6303 as the 6303 has 30% efficiency out as far as 850nm. Each CCD has its advantages I guess. The NABG puts a lot of people off the 6303.
