One pair of older Astro Physics Tube Rings.
They came off a late 80s 5" AP refractor that had a fatter
tube than the newer 5" AP scopes. They measure 5 7/8" in diameter
at their smallest point and will fit any 6" tube.
They are in excellent + condition.
$100.00 shipped in US.
I also have a home made G-11 style plate the rings fit on that I will sell for an additional $25.00. It is made very well but is not black anodized.
Paypal or money order acceppted.
