Meade ETX-90 Electric Focuser/OTA Field Back
Never used Meade electric focuser to suit ETX-90/105 plus ETX-90 visual back for field work. The ETX-90 EC can be deforked and the back replaced with the one shown. The OTA can then be fitted to a tripod or used as a guidescope. The motor speed is controlled by the handbox (needs 9V battery) or plugged into the Autostar hand controller. $75 plus postage.
