Note: This is an optical tube only designed for advanced astroimaging.
The iOptron Photron Ritchey-Chretien 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, perfect for color or monochrome imaging. A fixed position primary mirror eliminates image shift that occurs from focusing with other telescope designs. The iOptron RC10 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 10 knife edge baffles to diminish contrast-reducing stray light, improving the instrument in both visual and imaging uses. A RC10 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.
