A new mini-project for the Gaunt/Istar package:

Due to the push-to being so light and smooth I am finding that as I rack the focuser in or out with the heavy LVW eyepieces balance changes enough for the OTA to start moving.

I think I will have to build a sliding counterweight linked to the focuser so that as the focuser moves out the balance weight moves in and so on.

A small brass slider weight connected via a pulley should do the trick.???
