Part of a package I got a while back.
It was on the scope, but I replaced it with my Feather Touch Micro, so I can use the FT motor unit.
When it was on it seemed to work OK, but it is sold as is. Simple to fit, and instructions included.
Fits the likes of the Epsilons, the FS 102 etc. Make your enquiries if you have some other scope.
AU$150 posted.
