Howie Glatter Collimation Tools

Howie Glatter collimation tools are laser collimators and accessories for aligning Newtonian and other reflecting telescopes. Single-beam lasers come in 635nm and 650nm red or 532nm green, in 1.25", 2" and dual 1.25"/2" versions.

Holographic attachments project a cross hair, concentric circles or a square grid to check focuser and secondary alignment, and the BLUG and TuBLUG add the Barlowed laser method for the primary. A variable brightness battery cap lets you dim the beam.
