Howie Glatter 532nm 1.25" & 2" Laser Collimator

Howie Glatter Laser - For collimating your telescope with maximum precision

There are many laser collimators on the astronomical market, and many are made in a highly questionable manner. You see laser beams sliding like a splash of color on the primary mirror and tubes dancing the samba inside the focuser.

How can you talk about a well-collimated telescope? What is the use of even the most expensive telescope? The optics must be in order.

Luckily there is the solution: a Howie Glatter laser.

A cylinder tailored for the focuser
Depending on the model, the Howie Glatter laser features a 1.25" or 2" fitting. Unlike competing models, the diameter is calculated to perfection.

The laser is placed in the right spot - and consequently, you will also achieve the correct collimation.

Thin laser beam
A thin and well-defined laser beam is projected through your telescope. Depending on whether you are collimating during the day or at night, you can choose between a brighter or dimmer beam.

The laser diode is collimated and fixed during production. Even if the Howie Glatter laser suffers knocks, the collimation remains stable.

Even more precise: The 1mm aperture mask
The Howie Glatter laser is a well-designed instrument. Everything becomes clearer when you see the accessory. Various masks can be screwed onto the front, making collimation even more precise.

A mask with a 1mm hole in the center is included in the shipment. With this mask, the laser beam is further narrowed. When the mirror reflects the beam, you will see a central point around which concentric circles are created.

Accessories for the collimation laser
In addition to the 1mm aperture mask, other optional accessories are available for the Howie Glatter laser. A Barlow lens, a holographic reticle, an extension with a 45° matte plate - all elements that make collimation even more precise. With the holographic reticle, for example, you can precisely center the secondary mirror of a Newtonian telescope and easily adjust the offset. With the Barlow element, you can achieve an even more precise adjustment of the primary mirror.

The Howie Glatter laser allows you to collimate your Newtonian telescope to perfection. What advantages does this bring? You will have sharper images, greater contrast, and therefore you will grasp even the faintest details in the sky. Less frustration from collimation and more pleasure in observing.
