Answer directly from Losmandy













Hello Tom Hilton,

Thank you very much for the inquiry..

The Gemini II System is NOT being replaced. .ExploreScientific is using the G11 Mount made by Losmandy with theirown electronics. .These are 2 totally different drive systems :)

This is a partnership with ES not a replacement forany of the Losmandy products.

Kindest regards,.

Thanks Tom. Avalon instruments has developed their own starGo retrofit for the G11 as well. New motors and electronics that is.��

Yes Hanza, I know.. But both systems are stepper motors.. Theproblem with steppers is if you bump the

mount, and move it to another step of the motor,. without encoderfeedback the electronics has no

way of knowing that it is out of synch now... I don't know if eithersystem has encoder feedback, to

prevent this.



Also both systems requires an external computer to do GOTO's the wayI read it.. The Avlon will use

android based systems, but the Explore must be Win8.1 or Win10 basedtouch screens.



I am going to stick with my G2.



Tom

Tom,



Bumping the mount won't affect the steppers, but if the steppers stall, or lose some steps, the

electronics won't know about the problem. That's the advantage of servo motors, the servo encoder

provides feedback that the motor shaft is turning and has moved the correct number of encoder steps

to complete a commanded move.



To tell the electronics if the telescope was bumped, you need mount encoders which the Losmandy DSCH

kit, no longer available, would provide.
