BBROASTRO
Bubble Nebula (NGC 7635) & M52
A target I've been wanting to image for a long time, never had enough focal length until I recently had access to a 400 2.8 from Canon.
Shot using stock Canon 6D, EF 400mm 2.8 IS III and Skywatcher EQ6R Pro (unguided)
Imaging with stock cameras isn't ideal, thermal noise is a real problem after the exposure times needed. The longer exposures needed to get a reasonable signal really heats up the uncooled sensor. Mine during these summer months has hit 35-40c regularly which creates awful noise.
Getting as much data as possible helps lower these issues, but doesn't eliminate it. However, shooting with modern DSLRs does result in achieving star colour relatively easier compared to 12 and 14bit astro cameras.
This image is comprised of 21x600s Ha and 24x60s RGB exposures.
