Richey Chretien

Introducing the new Photron line of Ritchey-Cretien astrograph telescopes by iOptron.  Designed for today's astro imager, the Photron line of RC telescopes will deliver sharp clear image from one edge to the other.  iOptron had a longstanding reputation for creating and manufacturing sold, stable, accurate tracking, telescope mounts and it just makes sence adding high quality RC astrograph telescopes to compliment them.

The Photron line of Ritchey-Cretien design telescope's 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 colour and monochrom imaging.  a fixed position primary mirror eliminates image shift that occurs when focusing some telescope design.  The dual speed two inch linear bearing Crayford focuser can facilitate our optional ASCOM compliant electronic focus control delivering disturbance free focusing.  three 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 results for both visual and imaging uses.  Our 200mm, and 250mm models come with a top and bottom dovetail plates adding rigidity to the tube while providing attachments points for the mount and other accessories to be used.  Photron RC telescopes are available in 3 diameters and focal lengths.  150mm F9, 200mm, F8 and 250mm F8
