12-Inch f/8 Ritchey Chretien Reflecting OTA Telescope

Designed for today's astro-imager, the iOptron 12-Inch f/8 Ritchey Chretien Reflecting OTA Telescope delivers sharp clear images from one edge to the other. This truss-tube astrograph features low thermal expansion quartz primary and secondary mirrors with highly reflective dielectric coatings, and the RC optical design delivers coma, spherical and chromatic aberration-free results, perfect for color and monochrome imaging. With a carbon fiber truss backbone holding the optics firmly in place while keeping weight minimal, its open-air design results in rapid cooling, reducing wait time before use. A fixed position primary mirror eliminates image shift that occurs when focusing with other telescope designs.
