To deliver scientists the best astro-imaging system ever created, engineers at the Marshal Space Flight Center chose the Ritchey-Chrétien (RC) design as the primary optical system used on the Hubble Space Telescope. The RC optical system responsible for countless discoveries and spectacular images is now available in a telescope within everyone's reach. 

Introducing Photron, Ritchey-Chrétien telescope system by iOptron. 

Photron instruments are built to facilitate today's astra-imager in capturing the data necessary to create spectacular edge to edge sharp astro-images. To achieve this goal, The RC telescopes incorporate low-expansion quartz mirrors with 99% reflective dielectric coatings, fully baffled tube interior, and a smooth dual speed crayford focuser. Photron 250 system is packaged with an iOptron patented CEM60 Central-Balanced Equatorial mounts, a sturdy tri-pier and iOptron ASCOM compliant electric focuser for disturbance free operation.
