Product Description

The iOptron® Photron™ Ritchey-Chrétien 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, 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 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. A RC6 model comes with a Vixen style dovetail plates.

Ioptron RC8

I purchased this back in May. Finally had enough imaging time with it to give a review. The build quality overall is good. The top mount dovetail that comes with the scope is a little too close to the tube for my liking. I added 1/2 inch spacers to give it some rise this makes for a better handle to carry it around. The dust cover is plastic with some felt liner to hold it in place. This is not the best as it can fall off while in transport. Overall it is lightweight enough for a mount such as the AM3, HEQ5 or equivalent. Collimation was spot on right out of the box. No adjustments needed. With a generic GSO .75X reducer this brings the scope to f6 which works well from my location. Bright stars seem to have a halo around them, with or without filters. That could just be user error on my part. Not a fan of the crayford focuser which is not compatible with the ZWO EAF. There are 3d printed adapters that can make it work. I switched it out with a rack and pinion replacement which can hold more weight without slipping. Overall I would give this a 4 out of 5. Great value for the price. I would consider getting another one to run a dual imaging rig.
