The skyvector are "digital setting circles", which is a computer controlled "push-to" system. The encoders can sense where the telescope is pointing, so when you want to find something you punch it into the hand held interface and it tells you where to push the scope to find the object.
It certinally looks like a Gueng Sheng and they are supposed to have very good mirrors, Meade are using them for their Light Bridge aren't they?
