Cheers Louie. Yes the little faint galaxies show up often with this scope.

Thanks Peter. Weather is always the barrier.

John.
Thanks John. I like these groupings as well, it makes the field more interesting.

Nice shot!
I know what he means. I usually do much longer as well with galaxies.
In this case it was fairly bright and the 17 inch aperture and F4.45 which is very very fast for a large scope worked in my favour. I probably will add a bit more to it to see what I can get.

Good point Steve. I think I will add a bit more to it to see what it does.
I was mainly imaging Comet Garradd which can't wait of course so it wsa playing second fiddle at the time.

Thanks Rob. Its always a goal to try to process an image and make it look natural and like you haven't processed it at all. Not always successful in that regard but it is definitely a criterion that I keep in mind.

Thanks Tom. The weather seems to have gone into clear mode at the moment and no moon - woohoo!
