I'm using ASCOM with a driver for JMI NGC MAX computer to run with my planetarium program CdC
I had finally figured out how to get it working and it was great. I could center an object under the target rings, something like the 3 rings seen in a Telrad .and there it was, in the EP.
Then last night everything was off. Finally I saw where the gremlins in the computer had changed my location ! HUH? How they do that !?!
