Howie Glatter 650nm 1.25" Laser Collimator

Howie Glatter Laser - For collimating your telescope with maximum precision

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

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

Fortunately, there is a solution: a Howie Glatter laser.

A cylinder custom-made 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 sits in the right place - and consequently, you will also obtain the correct collimation.

Slim 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 the production phase. 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-thought-out instrument. Everything becomes clearer when you see the accessory. Different 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 dot 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 grid, an extension with a 45° matte plate - all elements that make collimation even more precise. With the holographic grid, 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 even more precise adjustment of the primary mirror.

The Howie Glatter laser allows you to perfectly collimate your Newtonian telescope. 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 observation.

The advantages at a glance:

• laser housing manufactured with precision
• custom-made for 1.25" and 2" sizes (depending on the model)
• laser diode collimated during the production phase
• shock-resistant
• thread for useful accessories
• 1mm aperture mask for laser beam reduction and concentric circles.
• 123A battery included in the shipment
• plastic case
