- Cleverly engineered 1.25" to 2" eyepiece adapter insures precise parallel alignment between drawtube and eyepiece to keep optics square to the telescope focuser
- Helps prevents angular misalignment of optics that may degrade image quality for visual observation, imaging, and collimation
- Simple to use and seats fully in drawtube without need for a clearance slot, with a non-marring clamps screw and zero in-focus loss
- Threaded for 2" filters
- Sky and Telescope 'Hot Product' for 2012
The Howie Glatter Parallizer is a 2" to 1.25" adapter that ensures eyepieces, imaging equipment, and collimating devices remain parallel to the drawtube of the focuser even when the clamp screw of the adapter is tightened. This is especially important in fast optical systems such as Dobsonians and refractors because an angular misalignment of even a few arcminutes can cause image degradation for visual observing and imaging.
While most 2" to 1.25" eyepiece adapters ensure optical elements are adequately centered from side to side, even if offset slightly by clamping, precise angular alignment in the drawtube is not assured by most adapters. The easy-to-use Howie Glatter Parallizer eyepiece adapter works by clamping each cylindrical surface between two parallel straight edges to secure stable alignment. Much like dropping a cylinder into a V-block in a car engine, the Parallizer provides a precise, tight, and wiggle-free fit. The adapter's non-marring clamp screw is set at 45 degrees and pushes the accessory down against the adapter flange when tightened.
The patented HG-Parallizer has zero in-focus loss, requires no screw slot to seat fully in a drawtube, and comes threaded for 48mm (2") filters. The Parallizer was selected as a Sky and Telescope Hot Product for 2012. As Sky & Telescope says, "It’s simple . . and it works . . !"
