Photron 200mm Ritchey-Cretien OTA (6112)

Description

The Photron line of iOptron Ritchey-Cretien design telescopes feature low thermal expansion quartz primary and secondary mirrors with ninety-nine percent reflective dielectric coatings. The RC optical design delivers coma, spherical, and chromatic aberration free results that is perfect for color or monochrome imaging. A fixed position primary mirror eliminates image shift that occurs from focusing with other telescope designs. The iOptron RC6 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. The RC8 model comes with top and bottom dovetail plates adding rigidity to the tube while providing attachment points for the mount and other accessories to be used.
