I am the original ownwer. This is the non-compression ring type. The black anodized barrel has a small blemish that is approximately 2-3mm. The optics are in excellent condition although they do have the usual dust associated with used optics. I have moved to 2" eyepieces and a BigBarlow, hence the sale of the Powermate. I can send pictures upon request. I want $125 and I'll pay shipping in the CONUS.
Thanks for looking,
