The Iris Nebula - NGC 7023
This is 3 hours of data on the Iris Nebula. It is a fairly bright reflection nebula in the constellation of Cepheus.
This is a stack of 58 x 3min ISO 800 subs from my back garden in Cambridge, UK. I have also removed dark and bias files but no flats.
This was the first time i have understood and completed a proper drift alignment. Trivial i know, but it has defeated me before and this was a big step towards me being able to get consistency with my imaging setup. So the 3 min subs all came out pretty much perfect. Was nice to be able to use 58 out of 70 subs taken. Wooohooo.
Any comments and criticism welcome.
