Revolutionizing Collimation for Cassegrain Telescopes

Since its inception in 1672 by Sieur Guillaume Cassegrain, the Cassegrain Telescope has undergone various transformations, leading to designs like the Ritchey-Chrétien, Dall-Kirkham, Schmidt-Cassegrain, and Maksutov-Cassegrain. Renowned for their compactness and simplicity, these designs traditionally rely on star collimation for alignment.

Now, backyard astronomers have a practical alternative for achieving precise collimation with the Advanced CT Laser Collimator. This innovative tool brings collimation within arm's reach, offering short-range capabilities for indoor or outdoor use, day or night. Featuring a large, clear target display, this collimator simplifies alignment diagnostics, ensuring accuracy without guesswork.

No Star? No Problem!

Traditional star collimation demands optimal observing conditions, including clear skies, stable temperatures, and suitable star visibility. Adjusting collimation involves tedious back-and-forth between the telescope's front and back, relying on unstable, defocused star images for reference. Artificial stars, while attempting to simulate real stars, cannot replicate true collimation conditions. Moreover, readjusting focus after artificial star collimation can introduce errors due to mechanical tolerances and mirror-flop.

The Advanced CT Laser Collimator eliminates these challenges by providing a clear visual cue with three laser dots projected onto a target. This allows precise axial alignment diagnostics without major focusing adjustments, saving valuable observing time and minimizing errors.

Collimate Within Telescope's Focal Distance

Unlike traditional collimation methods requiring long focal distances, our collimator utilizes a flat mirror at the focal point to double-pass both primary and secondary mirrors, magnifying alignment errors to a higher accuracy level. This near-field alignment process significantly reduces collimation distance, ensuring convenience and accuracy.

Cost-Effective Precision Collimation

Our collimator employs state-of-the-art laser optical alignment technology, offering rough alignment functions comparable to costly interferometers at a fraction of the cost. Three collimated lasers spaced evenly simulate a distant star's light path, passing through your telescope's optical elements for a comprehensive double-pass diagnostic reading.

Precision Engineering for Reliable Performance

Crafted from aerospace-grade aluminum and precision CNC machined, our collimator boasts a durable, lightweight design. Thermally stable and portable, it simplifies setup and ensures accurate collimation for all Cassegrain telescope designs.
