Buyer beware! While this helical focuser takes a 1 1/4" eyepiece, the other end seems to be designed for a specific, unknown optical device, adn does NOT fit a regular eyepiece mount. I have bought two of these, because the ads appeared to be different, but they were the same - don't fit anything I have.
