Thanks people.
I cant autoguide as the cost to set it all up would be beyond me. My mount has no motorised Dec, so I make Dec adjustments by hand. The RA drive on the mount has a old 240v Synchronous motor, I use a simple RA Drive corrector that varies the speed of the motor by varying the frequency above or below 50 Hz. Theres no input for autoguiding in the Corrector. I'd love the idia of starting exposures then leaving the scope unattended, but there is too many things to do to set that up with my rig
