Optec's new 4-port Instrument Selector allows the remote observatory user the ability to remotely select any of four instrument packages attached to their telescope.

This is Optec's new 4-port instrument selector.   The photo shows a top view of the selector with two different CCD cameras, a single channel SSP photometer, and a separate TCF-S focuser and eyepiece.  Any variety of instrument packages can be configured and used.

The 4-port selector is being demonstrated in the video below on a Meade 8-inch Schmidt Cassegrain telescope. However, it's really designed for at least a C11 class telescope. This is a robust design and intended for permanent observatory instruments only.here are four instrument ports - three 2-inch ports and one 3-inch port available with the Perseus.  In the video below, the mirror is not yet attached to the prototype but it is an 1/8th wave first surface elliptical mirror with a 3-inch minor axis.

The embedded circuit has a single push button interface for use at the telescope and an RS232 DB9 interface for remote control.  LED indicators show the currently selected instrument.
