Denkmeier Standard Deepsky Binoviewer with padded case and all caps, as shipped in 5/2003. Includes 1.25" refractor OCS and part "T", allowing 1.2X to 3X use with any size diagonal. Excellent condition and a real joy to use, but I only have a small refractor and this binoviewer would be better for someone with a slightly bigger scope.
I think you may need an additional extension tube to use it at 1.2X with a newtonian; as it is, it should work at 2.5X in a newtonian, and the additional part to allow it to work at 1.2X should be pretty cheap, but I haven't used it with a reflector so I'm not sure about that.
A few eyepiece pairs are available if you need them to get started:
1 set of 25mm GTO plossls, $25 for both;
1 set of 7.4-22mm zooms, $85 for both
Paypal (no fee) or cashier's check/money order. Let me know if you have any questions. Thanks,
