I just picked up an older Meade StarNavigator 114mm f8.8 Newtonian telescope. It has a strange accessory on the OTA that I'm unable to identify. It is plugged into the AUX port of the motorized mount and has a 1/8" phono jack and two adjustment screws. At first I thought maybe it was a star tracker but it doesn't seem to have any optics on it.
Can anyone help me figure out what it is? Maybe it is a skew motion detector?
