After having a bit of a annoying time with the goto system on my XT14g, I decided to ditch the synscan controls and turn the scope into a push-to with the possibility of adding a ServoCat system later on.

This involved some talks with Gary at Wildcard about fitting an ArgoNavis and after half a day of mucking about with pulling the mount apart and then a week of Gary making some encoder adaptors. I then became one of the AN elite

I found that whilst pushing the scope in Azimuth was fine, the Altitude movement was a bit stiff so I used the old motor on the Alt axis to drive the scope in fine steps (by making a very basic variable voltage controller).

As I use SkySafari for most of my charting requirements I had to find some way of fitting all these nice goodies to my scope. These images are what I've ended up with so far. I still have to tidy up the wiring and if the motor controller is not fine enough then I'll look at some sort of PWM drive for now until I decide to go the ServoCat.
