Had my first attempt at Centaurus A last night at the end of a long night. I set out to tri-colour but only captured the red and green before the clouds rolled in so here's just the red channel.
Good question Eric - honest answer is I don't know. I did the post processing in PS with Carboni actions - I did this late last night and can't remember exactly what I did but I think I used the "lighten only DSO and dimmer stars" action.
Nice and sharp!
pitty about the clouds rolling in!
that always worries me if I went to RGB imaging. Sure enough those clouds would roll in as soon as you put in the last filter
cheers
Thanks Marc, Gary and Alchemy. I had a look at the green channel tonight and it had a lot more noise than the red. I was told imaging galaxies in mono through a red filter was the way to go although that's not what I had in mind last night.
RGB can take a long time and the Brisbane weather sure is unpredictable at the moment.
