Hi Lee,
Good to see you up and running with the new rig!!

Always takes a while to sort out the bugs etc..but you are off to a good start! A little too much unsharp in the 2min pics, much better in the 1 min stack. I ussually leave the unsharpening as one of the last processes as if you adjust curves, contrast after you`ll make these dark halos more obvious..
A great start Lee

if you can go to 4-5min exposures you will get plenty of detail. Have you got it setup to guide?
My first night out was a bit of a disaster too, but last night managed to sort some out and got at least 6 good frames!!. Will post soon!
Cheers Gary
