A new-in-the-box 2" diagonal, Owl Optics, high-end reflective mirror, less than 1/4 wave, perfectly aligned w/ brass compression ring, all metal construction but fairly lightweight. Mount tube is chrome steel w/ a safety retention ring. Capped both ends (nice ones). Refractor or SCT function. A really fine piece, easily comparable to the much higher priced labels. I ended up with two of these, keeping one for my SCT, letting this one go for $85, shipped conus, paypal accepted. Thanks for looking.
