I bought this from Scopetronix a couple of weeks ago and have not used it. It is beautifully made and will hold any 1.25" eyepiece. Includes a barlow-like adapter to double the power of the eyepiece you are using for eyepiece projection. Also, you can use this without and eyepiece for prime focus with or without the barlow adapter. I paid $129.00 plus shipping, but will sell for $90.00 and I'll pay to ship FedEx 2nd day in U.S.
