Sky & Telescope Hot Product 2019

 The new TCF-LEO is the newest in our line of temperature compensating focusers.  This thin low-profile focuser has a minimum thickness of only 1.25" and 0.35-inches of travel or about 9mm.

We anticipate the TCF-LEO will help many imagers struggling with minimal back-focus on scopes such as the Celestron EdgeHD C1100.  TCF-LEO is designed to fit between the mirror lock-knobs on the C-11HD and will work well with the Innovation Foresight On-Axis Guider as well as the large Perseus 3-inch port. Click here for more information.

Perseus 4-Port Instrument Selector

Optec's Perseus 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.
