Howie Glatter Laser Collimators are precision machined to fit your focuser perfectly. This 1.25" collimator is recommended for use in 1.25" focusers. It may be used in a 2" focuser with an accurate eyepiece adapter, and the adapter itself can be checked for accuracy by rotating the adapter and reclamping it, then seeing if the laser spot wanders.

The Laser itself is tuned to a higher brightness than others. Each one comes with a 1mm Aperture Stop for a pin point laser dot. The 650nm collimators are fine for use at dusk in subdued light. The 635nm laser is more expensive, but it enables Barlowed or holographic collimation in higher levels of ambient light. All of the collimators are powered by a CR123A lithium cell, giving about 40 hours of service. They come with one battery, a plastic case and collimation donuts.

The Holographic and Barlow attachments (Sold Separately) can be used with any Howie Glatter collimator by simply removing the 1mm aperture stop at the end of the collimator and screwing on the attachment of choice.
