This is an iOptron Photron 6" Ritchey-Chretien OTA in excellent condition, with clean optics and body.  There are some minor scratches on the tube, but obviously, this won't affect your use of the scope.  See the photos.  We have taken this minor condition issue into consideration in the pricing.  It comes with 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.  

This is available for pickup in our showroom; or, we can ship this to you for a $29 shipping charge.  

 


 

The iOptron Photron Ritchey-Chretien 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.
