Description

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.
