iOptron 6" Photron RC Ritchey-Chretien Telescope OTA
iOptron Photron 150 Ritchey-Chretien Optical Tube
iOptron Photron™ telescopes feature a Ritchey-Chretien optical design that boasts primary and secondary mirrors with low thermal expansion quartz and 96% reflective coatings. The primary mirror is fixed to prevent the image shift encountered with other telescope designs. This Photron RC6 comes with 2" dual-speed Crayford focuser and three focuser extension rings to allow "flex-free" solid extension as a way to eat up any unnecessary back focus. Equipped with an internal multiple knife-edge baffle system, the Photron RC6's steel optical tube enhances contrast by reducing stray light, improving the instrument for use both visually and photographically. A Vixen-style dovetail plate is included with the RC6 model.
