Used TPO 6-inch Ritchey-Chretien

This is a TPO branded RC6.  This is the same as other brands, with the tube painted a different color for this TPO clone.  The information for the iOptron version is below. 

It is in excellent condition, with clean optics.  The tube has some minor scratches, but not anything that stands out.  It comes in a hardware case with foam, and three extension tubes:  two 1-inch tubes, which attach before the focuser, and a third 21mm tube, which attaches on the end of the focuser.  

The iOptron Photron 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, 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.
