Telescope House are pleased to announce the new Revelation 8" RC Optical Tube Assembly OTA. Bringing you a perfect marriage of optical quality and affordibility.

Revelation Ritchey Chretien systems are excellent Cassegrain-configuration optical systems which are great performers for many different types of astronomical observation, but are particularly well suited for astrophotographic purposes. Both the Primary and Secondary mirror of the Revelation RC are Hyperbolic in design. A true Hyperbolic RC system is superior to a standard Schmidt-Cassegrain and other optical designs in many important respects: a well-designed RC will have no Coma (elongation of stars) around the edge of the field; an RC will give a sharper on-axis response than most SCTs or Newtonians; they are completely false colour free; they have no front corrector plate, thus reaching thermal equilibrium quicker and cutting down dramatically on dewing issues.

The Revelation RC design features a fixed Primary and Secondary mirror, negating any mirror shift and related optical-mechanical weaknesses. These RCs feature a 2" fitting (with 1.25" step-down ring), 360°-rotating, 1:10 geared ratio, graduated Crayford focuser for precise focus, with generous travel for the attachment of a whole host of visual and photographic accessories. The focuser will also take up to 5kgs of accessory load. Also included with all the Revelation RC range are 2x 25mm and 1x 50mm focuser extension tubes for use with 2" and 1.25"diagonals respectively. These fit between the telescope and the focuser to remove the possibility of flex which can be an inherent problem with standard extension tubes. The entire interior of the OTA is lined with CAD-optimised knife edge baffles, and the internal fixtures blackened to suppress reflections and increase contrast.

This version comes with a Vixen-style full length rail, for easy balance of the system on many commercially available mounts.

Please note, a finder is not supplied with this telescope, but the inclusion of a Synta-style finder dovetail braket allows the easy fitting many different finder options.
