iOptron Photron RC10 - 10 inch Ritchey-Chrétien Astrograph Telescope OTA

Introducing the new iOptron Photron 250 mm (10") Ritchey-Chretien (RC) Astrograph! iOptron has long been recognized for producing solid, stable, accurate tracking telescope mounts, and now they have added three new RC Astrograph telescopes to their well-known line. This Astrograph is the model 6113, having an aperture of 250 mm (10 in) and a focal ratio of f/8 for a focal length of 2000 mm.

The iOptron® Photron Ritchey-Chrétien design telescopes feature low thermal expansion quartz primary and secondary mirrors with ninety-nine percent reflective dietetic coatings. The RC optical design delivers coma, spherical and chromatic aberration free results, perfect for color or monochrome imaging. This model, the iOptron Photron RC10 - 10 inch Ritchey-Chrétien Telescope OTA also includes built-in cooling fans for the primary mirror to help quickly cool down the mirror surface, to reduce thermally induced turbulence within the tube itself. Three fans cool the mirror and run on batteries, with an included battery holder.

A fixed-position primary mirror cleverly eliminates image shift that occurs from focusing with other telescope designs. The iOptron RC10 200 mm Astrograph comes with a 3.3" dual-speed linear-bearing Crayford focuser. Three focuser extension rings are provided for a “flex-free” solid extension as a means to take up any unneeded back focus. Its steel tube is equipped with 10 knife edge baffles to diminish contrast reducing stray light, improving the instrument in both visual and imaging uses. This iOptron Photron 200 mm Ritchey-Chretien (RC) RC10 Astrograph model comes with both top and bottom Losmandy-style dovetail plates adding rigidity to the tube while providing attachment points for the mount and other accessories you may wish to use.
