iOptron Photron RC8 OTA

The iOptron Photron RC8 is a Ritchey-Chrétien astrograph with a 200mm primary mirror and a 1624mm focal length.

iOptron's Ritchey-Chrétien telescopes have a much flatter field of view than other telescope designs, with zero coma and false color, making them particularly well-suited for astrophotography. The long focal length of iOptron RC telescopes is beneficial for imaging galaxies and planetary nebulae. Both mirrors are 99% reflective and are aluminized and quartz coated.

The telescope has a 2" dual-speed Crayford focuser. The primary mirror is permanently mounted, so there is no mirror flop that is common for many other Cassegrain telescope designs.

ASCOM-compatible iOptron focus motor for RC telescopes available separately.
