Since the advent of Astro-Physics GOTO mountings, owners of the 400GTO, 600EGTO and Mach1GTO have hung their GTOCPx control boxes in a special pouch, usually from one of the pier knobs. The 900GTO and 1200GTO were big enough to have the control box permanently mounted on the RA axis, but these smaller mounts didn't have that luxury. Now, owners of these mounts who have either a GTOCP2 or 3 control box have another option: The Control Box Adapter for Piers and Tripods. (sorry if you have a GTOCP1!) This Control Box Adapter is included with all new Mach1GTO mounts shipped after April 15, 2007.

The Control Box Adapter features thumb screws on one end and a dovetail on the other to fit the dovetail grooves on your control box. The adapter can be mounted from four different attachment points including the top one which angles the control box out a bit to clear legs or struts. The adapter also can be mounted with either end up or down if a particular orientation works better for your situation. A full assortment of fasteners is provided for the various mounting applications.
