hi,
could someone explain how the concept of adding relays to a mounts hand controller box for autoguiding works or how the older mount hand controllers perform manual guiding corrections
what i don't understand is that for autoguiding, the mount has to be tracking so the RA motor would be rotating at the predetermined tracking rate.
so how would the RA+ and RA- relays or buttons work for manual or autoguiding as RA is already on.
So does RA+ just increase the motor speed by a small increment?
I was looking at these instructions for the shoestring handcontroller modifications to add an st-4 port to a mount that doesnt have an st-4 port.
