RCOS 2005 Model "Professional Series" Equatorial Fork Mount. Specifically designed for the RC Optical Systems 20RC and 24RC.

Carbon Truss 32 inch f/8 Ritchey-Chrétien. Estimated one year delivery from time of the order. Price is for the OTA only, mount not included. A new alt-az mount is in design and should be completed by the end of 2006. Price on the mount TBD.

Designed specific to the 24RC. (100mm Model Illustrated).

RC Optical Systems T-Thread to Astro Physics Adapter.

Mounting Plate for Field Flattener/Corrector

Allows for a "threaded" fit of your SBIG STL Camera to PIR, AP 2.7 inch focuser, AP extension tube, and AP .75x telescompressor.

The RCOS (AP 2.7 inch compatible) "Male to Male" threaded adapter. The threaded adapter is CNC machined, and is black anodized. Uses .375 inches of back focus. Allows for a male to male "threaded" fit of your RCOS and AP 2.7 inch accessories.

Optional carbon light shroud around primary mirror.

RC Optical Systems can add an Astro-Physics focuser to your scope. These are without doubt among the finest focusers available. In addition to silky smooth action, the focuser allows use of Astro-Physics accessories including focal reducers and barlows.

Airline carrying case for the 12.5" RC telescope, tube or truss models.

Eliminates field curvature present in all reflective telescopes while eliminating astigmatism and reducing spot size.

NEW! RC Optical Systems is proud to introduce its new Off-Axis Guider.

The Telescope Command Center is a combination of hardware and software designed to control the peripheral functions of the RC Optical Systems line of telescopes. The TCC hardware consists of a processing unit attached to the telescope and a hand held display unit used for user control. The TCC can also be simultaneously controlled via computer through its serial port.

 

The RCOS 70mm Series Precision Instrument Rotator. Extreme performance ensures absolute positioning! Controlled by the Telescope Command Center. Large 2.7 inch clear aperture.

In early 2000, RCOS designed, developed, and manufactured a Dichroic Beam Splitter (DBS) to permit "on-axis" Adaptive Optics guiding. We have since redesigned the DBS to accommodate two imaging cameras, rather than a single imager and a guider. For example, a Visible Light camera and NIR / SWIR camera. Or an SWIR and MWIR camera. These new model Beam Splitters are commercially available as of October 2006.
