Description

The Photron line of iOptron Ritchey-Cretien design telescopes 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 that is perfect for color or monochrome imaging. A fixed position primary mirror eliminates image shift that occurs from focusing with other telescope designs. The iOptron RC6 comes with a 2" dual-speed linear-bearing Crayford focuser. Three focuser 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 knife edge baffles to diminish contrast reducing stray light, improving the instrument in both visual and imaging uses. The RC6 model comes with a Vixen style dovetail plate.

Customer Reviews (4.6 / 5 · 5 reviews)

Sofia N. ★★★★★

The quartz mirrors held thermal equilibrium much faster than my old glass scope, which made a huge difference during cold winter nights. The dielectric coatings really pull out subtle nebula details I'd never seen before.

Andrew D. ★★★★★

I was blown away by how sharp the stars appeared right out of the box, even before collimation. The quartz mirrors with dielectric coatings really do keep the image contrast high and thermal stability rock solid.

Mia T. ★★★★★

First light on this RC was a revelation — the 99% reflective coatings really pull in faint nebula detail I couldn't see with my old SCT. The quartz mirrors held collimation perfectly even after cooling down on a chilly night.
