More product information
The Glatter Parallizer 2" to 1.25" adapter is the solution to a subtle problem that may be robbing you of some of your scope's visual and imaging performance. 

Eyepieces and imaging systems work best when all of the components are perfectly square to your telescope's optical axis. This is particularly important with ultra-fast focal ratio Newtonians, advanced optical design astrographs such as Ritchey-Chrétiens and Dall-Kirkhams, larger imaging chip cameras, and precision collimating tools.
 
An angular misalignment (a tilt) between the accessory and the drawtube axis of even a few arc minutes can be detrimental to collimation and imaging. A consistent and repeatable parallel alignment of your accessories within the focuser drawtube is therefore essential for tack-sharp collimating and for achieving a sharp focus across a CCD or DSLR's imaging chip. 

Unfortunately, conventional 2" to 1.25" adapters often tilt slightly when tightened into a focuser. The Glatter Parallizer 2" to 1.25" adapter has a patented design that insures precisely parallel alignment between a 2” focuser drawtube and a 1.25” accessory. 

The Glatter Parallizer works by clamping each cylindrical surface (both the body of the adapter and the accessory that is slipped into the adapter) between two parallel straight edges. Because the inner and outer pairs of straight edges are parallel to each other to high accuracy, a precise and consistent parallel alignment between the drawtube and the accessory is assured. The inner pair of straight edges can be seen by looking down the 1.25” barrel, as shown in the feature photo above.

The adapter's non-marring clamp screw is set at a 45° angle, which pushes the 1.25" accessory down into the Parallizer and against the adapter's flange when tightened. The Parallizer has zero in-focus loss, and doesn’t require a clearance slot in a drawtube to seat fully. It is threaded for 48mm (2") filters. The Glatter Parallizer was named a Sky & Telescope magazine "Hot Product for 2012."
