iOptron 10" Photron RC Ritchey-Chretien Telescope OTA
iOptron Photron 250 Ritchey-Chretien Optical Tube
iOptron Photron™ Ritchey-Chretien designed telescopes boast primary and secondary mirrors consisting of low thermal expansion quartz with 96% reflective coatings. Ideal for both color and monochrome imaging, RC telescopes produce results that are free of coma, spherical aberration, and chromatic aberration. The steel optical tube features multiple knife-edge baffles on the inside to reduce the impact of stray light and boost contrast, thereby enhancing the instrument for both visual and imaging applications. Comes with a linear-bearing 3.3" dual-speed Crayford focuser and three extension rings to eliminate any redundant back focus by providing a "flex-free" solid extension. Includes both top and bottom dovetail plates for extra rigidity as well as mount and accessory attachment points.
