The iOptron Photron™ RC6 offers a compact and affordable entry into true Ritchey-Chrétien optics, making it an excellent choice for astrophotographers and visual observers seeking high-contrast, coma-free performance. With a 6" (150mm) aperture, low-expansion quartz mirrors, and a solid steel tube featuring knife-edge baffles, the RC6 delivers sharp, aberration-free images in a portable package.
Precision Optics for High-Quality Imaging
At the heart of the RC6 is a true Ritchey-Chrétien optical system utilizing hyperbolic primary and secondary mirrors made from low thermal expansion quartz. These mirrors are coated with high-reflectivity dielectric coatings, ensuring excellent contrast and brightness. The fixed-position primary mirror eliminates image shift during focusing, providing consistent performance for both imaging and visual observing.
With a focal length of 1370mm at f/9, the RC6 offers a versatile balance between magnification and field of view, making it suitable for a wide range of astronomical targets.
Solid Steel Tube with Knife-Edge Baffles
The RC6's steel optical tube assembly is designed for rigidity and durability. Internally, the tube features multiple knife-edge baffles that effectively suppress stray light, enhancing contrast and improving image quality. This design ensures that the telescope performs optimally in various observing conditions, whether in a backyard observatory or at a remote dark-sky site.
Dual-Speed Crayford Focuser and iEAF Compatibility
Equipped with a 2" dual-speed Crayford focuser, the RC6 allows for smooth and precise focusing, essential for high-resolution imaging. The focuser supports iOptron's optional iEAF electronic automatic focuser (sold separately), enabling automated focusing through ASCOM-compatible software—a valuable feature for remote or automated observatories.
To accommodate different imaging setups, the telescope includes three threaded extension rings (two 1" and one 2"), allowing users to achieve the necessary back focus without compromising stability.

Observing Tip
The RC6's compact size and lightweight design make it an excellent match for mid-class mounts like the iOptron CEM26 or GEM28. Its high-quality optics and solid construction provide a reliable platform for both visual observing and astrophotography, especially when paired with the optional iEAF for automated focusing.
Solar Use Warning
Never look at the Sun through this telescope—or any telescope—without the proper solar filter installed. Permanent eye damage or blindness will result. Always use approved filters designed specifically for solar observing.
