Also what sized scope aperture are you using?

Andrew, I use an alt azi mount and an 80mm scope.
You're good for exposures up to 20sec, which is what I take using a dslr with the same setup.
So the 2.56 sec exposures with the Gstar are no problem at all.
DeepSkyStacker takes care of any field rotation.
There's an article here that goes into more detail about how I capture.
