Quickly took the scope out tonight, didn't mount it though as i didn't want to cart the mount out for 15mins of testing - and there is a bit of cloud out.
Hopefully tomorrow the sky will be a bit better and since it's the weekend i'll be able to spend awhile with it playing.

Still can't figure out how exactly dark frames in PHD are meant to be used.

Tried to get focus and see if i could find any stars but i didn't have much luck. The only thing i was able to find was Jupiter (nice and bright).
The hot pixels are very annoying (and for a new camera, i think it does have a fair few hot pixels).
I watch videos like: http://www.youtube.com/watch?v=XPvHQhdLJ4o
and

There display is very dark with obvious stars in view. IF i have my on-screen gama (slider in PHD) set to 1/4 from the left i get a very bright screen that you probably won't be able to discern any stars. If i go down the other end to 3/4 from the left it is dark but all i can see are hot pixels. Sure the scope probably was out of focus but i was expecting to see at least some blobs of out-of-focus stars.

Oh and another question; what do people use for camera gain when selecting the camera?
ASCOM defaults to 50% gain.

Thanks.
