G'Day Asi,
I'm getting better at polar aligning! I drift aligned last night but didn't use K3 to really do the fine tuning. I did notice some drift while I was imaging, so while I could've gone longer I think, I'm not sure by how much.
I reckon drift aligning with K3 is just the bees knees, but I find that by myself it can get a bit busy when trying to measure the angle of the camera... it helps to have someone else there to start / stop the camera angle measurement routine in K3 - or one of those little remote controls like 1ponders has (I think Robby makes them??

). Not sure if they'll work on a CG5.
Al.
