Thanks Ken,
that's what I was after..
Yes, it is the GT... probably should have stated that from the get go...
I didn't want to risk plugging stuff in & blowing something up... I'm neck deep in it with my wife for the purchase of the mount... last thing I needed was to screw that up...
Now, safe in that knowledge, I will have a play with it using a short USB extension cord to see what it does before I decide if I'm going to incorporate it into my imageing... if I go that route & end up using my computer to control the mount then it will make absolute sense to move image capture onto my computer too...
Man, this whole AP thing is such a rabbit hole...
All I ever wanted to do was capture what I could see at the EP to share with friends... but, it's addictive...
