comments and suggestions welcome
In particular-I seem to be have become too set in my ways to go to a dark site so I image in H Alpha from home
I capture at 1x1 with an H Alpha filter and then discard green and blue channels
(this is a one shot colour camera)
would I be better capturing in say 2 x2 binned mode and then using Drizzle to upscale?
oh and image technical details aside isn't this an absolutely glorious object-also called the Crab nebula for fairly obvious reasons.
thanks for looking
