This is the University Optics 2.14" 1/10 wave secondary mirror for newtonians in the UO secondary holder with spider. The mirror is dusty but otherwise excellent, holder and spider in excellent condition as well. Spider was made for 12" tube.
New is $58.95 (diagonal) + $39.95 (holder and spider) = $98.90 without shipping.
I would like $50 shipped in CONUS - less than half new. Selling simply because I'm not using it anymore. Please feel free to e-mail with questions.
