Parallax 12" standard tube rings with Losmandy 19" universal dovetail plate. These tube rings and plate are less than one year old showing only normal wear at the locking bolt slots. I have doubled up on the felt liner because my tube was a little undersized. I will include a new roll of felt so you can replace it if you need to. The rings are drilled and tapped for the plate (hardware included). These are perfect for mounting a 10" Newtoninan on a Losmandy G11 (must have a 12" OD tube).
New the rings are $185, the plate $75. Asking $195 (firm) for both. Shipping charges are extra.
