iOptron Photron RC6 - 6 inch Ritchey-Chrétien Telescope OTA

Introducing the new iOptron Photron 150 mm (6") 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 6111, having an aperture of 150 mm (6 in) and a focal ratio of f/9 for a focal length of 1370 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.

A fixed-position primary mirror cleverly eliminates image shift that occurs from focusing with other telescope designs. The iOptron RC6 150 mm Astrograph comes with a 2" 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 knife edge baffles to diminish contrast reducing stray light, improving the instrument in both visual and imaging uses. This iOptron Photron 150 mm Ritchey-Chretien (RC) RC6 Astrograph model comes with one Vixen style dovetail mounting plate.
