Omegon Laser Collimator 1.25″ Rev. B

Omegon Laser Collimator 1.25″ Rev. B

The Omegon Laser Collimator 1.25″ Rev. B is a reliable tool for fast and accurate collimation of Newtonian telescopes. Only a properly aligned optical system can deliver the full performance your telescope is capable of - sharp stars, high contrast, and maximum resolution. This collimator is an essential accessory for every owner of a Newtonian reflector, whether a beginner or an experienced observer.

Design and Construction

The collimator body is machined from precision-cut aluminum, ensuring durability and a long service life. The front aperture emits a laser beam directed straight at the telescope optics. A side window allows you to observe a disk oriented at a 45-degree angle with a central hole - this makes it easy to verify whether the laser beam returns to its starting point, which is a clear indicator of correctly aligned optics. The entire unit is lightweight, compact, and very simple to operate.

Easy Single-Person Collimation

The collimator is designed so that the entire alignment process can be completed by a single person without any assistance. Simply insert the collimator into a 1.25″ focuser and it is immediately ready to use. Detailed step-by-step instructions are included, explaining exactly how to collimate a Newtonian telescope. Thanks to the clear and concise guide, Newtonian telescope collimation using a laser collimator is achievable even for a complete astronomy beginner, and the whole process takes only a few minutes.

Pre-Aligned Laser and Fine-Tuning

The laser is supplied pre-aligned and is ready for immediate use straight out of the box. If fine adjustment is ever needed, it can be performed using three evenly spaced holes arranged around the circumference at 120-degree intervals, which are sealed at the time of delivery. This fine-tuning option is especially useful after prolonged use or following a mechanical impact. Battery replacement is simple - just unscrew the small cap on the rear of the collimator and replace the CR2032 battery.

Why Collimation Matters

Collimation is the process of aligning a telescope's optical elements so that their axes coincide precisely. In Newtonian reflectors, regular collimation is essential because the mirrors can shift slightly during transport or as temperatures change. Misaligned optics produce blurred star images, reduce contrast, and prevent you from using the full potential of your instrument. The Omegon Laser Collimator 1.25″ Rev. B solves this problem quickly and reliably - the result is always the sharp, high-contrast image your optics are capable of delivering.
