This is a polar finder scope from a CG-5 that I had a spare of, so I machined an adapter to fit my Losmandy G-11. The finder scope slides into the adpater and the adapter then screws onto a couple of the internal threads of the Losmandy. Has the standard reticle with a large circle 1 degree from the crosshairs, and a second small circle where you place Polaris. The nice thing about this finder is you can leave it in the Losmandy and put your cap back on. Itr is not illuminate.
I'm not sure what it is worth with the adpater, so please make me an offer above $25. Thanks, Fred
