Perseus 4-port Instrument Selector
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.
There 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.
The final instrument selector will be fully anodized and available from Optec in late May or early June.
