The Glatter Sling ™ for Obsession and other Dobs is a new development in primary mirror edge support systems that eliminates the problems of astigmatism and miscollimation present with many commercial and ATM slings.

The tuBlug™ is the answer for those who want to Barlow-collimate their primary from the back of the scope, but have a solid tube Newtonian, or can't be bothered to slide their shroud up.

The most important specification for a laser collimator is the accuracy and stability of the laser beam alignment with the cylindrical axis of the collimator body.

The tuBlug™ is the answer for those who want to Barlow-collimate their primary from the back of the scope, but have a solid tube Newtonian, or can't be bothered to slide their shroud up.

The Blug is Howie's newest Newtonian collimation accessory (Blug is short for Barlowed collimation plug).

Introducing the SCT Parallizer®. This new application of Howie Glatter’s patented Parallizer® principle raises the bar for performance.

Howie Glatter now offers an innovative 2-to-1¼-inch adapter that properly squares your eyepieces, collimation devices, and cameras to the optical axis in your 2-inch telescope focuser.

A cross-hair and circle “scope” pattern is available that spans 10 degrees. It has utility for non-Barlowed, conventional Newtonian primary collimation, where the primary is adjusted to return the reflected central laser beam back into the laser aperture

Concentric Circle Projection Attachment.
A brighter pattern spanning 10 degrees, best for Cassegrain scopes slower than f/5.6

Square Grid Projection Attachment. A wide pattern spanning 21 degrees, best for fast scopes down to f/2.7

Attaches to laser aperture for making the primary mirror adjustment quick, efficient and compact.

T-adapter with Howie Glatter's Parallizer Patent alignment feature allows your image train to stay parallel
