Description

I recently uploaded a version shot with a f/3.8 Riccardi-Honders composed of 23.50 hours of lights. This adds 33.50 hours of data from a f/6.3 Tak FSQ. The critical subs were the OIII subs and both scopes took 1800s subs: 29 from the RH and 55 from the FSQ. Given the speed differences a FSQ sub collected a bit more than a third of the light of a RH sub of equal duration. So, the resulting exposure only increased by 69% despite increasing from 14.50 hours of OIII to 42.00 hours. These data sets were mutually rotated so I had to crop down to the point where much of the Flying Bat was cut while preserving the Squid. All in all I like my processing of the RH only version better,
