1. Universal Compatibility: Designed to work with all types of telescopes, reflectors, refractors, for Dobsonian, for Mak‑Cas, and for . It fits on astronomy telescopes with an outer diameter of 104‑146mm and can be easily attached to any telescope with the 3 bolt setup.
2. Focusing: Eliminate guesswork in focusing with the telescope focusing mask. It overcomes visual conditions and facilitates fast and easy optimal focus for your telescope.
3. Secure and Centered Positioning: The 3 metal posts clamp onto the telescope, preventing slipping and keeping the mask perfectly centered. The 3 post mount allows the mask to stay centered while accommodating a wide range of telescopes.
4. Efficient Star Focusing: As light passes through the focusing mask, it diffracts in 3 different directions, creating 3 pairs of star spikes. The pattern of star spikes shifts as the telescope's focus adjusts, indicating star focus when the 3 spikes align.
5. Lightweight, Resilient Design: The focusing plate is crafted using lightweight aluminum alloy and is just 1mm thick. It ensures the balance of the telescope isn't disrupted and guarantees durability and longevity.
