The Lumicon Laser Pointer Bracket for Refractor Telescopes is designed to hold red and green lasers, provide pinpoint accuracy, and maintain its alignment when re-attached using this quick release bracket.

It has a small base to take up less space on your refractor scope.  With a radius-cut of 1.75", this base fits snugly on most refractors, and is mounted with the included industrial-strength double-sided tape.

This model (LS2055) has a base which is 1.12" wide at the bottom, 0.88" wide at top, and 1.5" in length.  The height to the top of the ring is 2.6".
