[PERFECT FIT FOR 103MM TELESCOPES] Designed specifically for telescopes with a 103mm internal diameter, this Bahtinov mask ensures a snug fit without wobbling, for maintaining diffraction pattern accuracy during focusing. Ideal for reflector, refractor, Dobsonian, and Cassegrain telescopes.
[CUT ALUMINUM ALLOY CONSTRUCTION] Crafted from high-quality aluminum alloy, this mask features precise cut diffraction gratings for unambiguous star spikes. The material is lightweight yet durable, to cold temperatures, and won't scratch your telescope tube.
[INSTANT ACCURATE FOCUSING] Eliminates guesswork by generating clear diffraction spikes that align perfectly at optimal focus. Essential for astrophotographers using DSLR or CCD cameras, where sub-arc-second precision is required for sharp deep-sky images.
[SECURE NON-SLIP MOUNTING] Features an adjustable clamping system with silicone padding to grip your telescope tube firmly without slipping or rotating during focus adjustments. Ensures the mask stays centered for consistent results.
[UNIVERSAL TELESCOPE COMPATIBILITY] Works flawlessly with all telescope types including -Cassegrains (SCTs). The pattern creates three distinct diffraction lines that converge precisely when focus is achieved, even in challenging visual conditions.

وصف

1. Universal Compatibility: Fishbone focusing mask is suitable for all types of telescopes, including reflector telescopes, refractor telescopes, support for Dobsonian telescopes, and support for Cassegrain telescopes, for 103mm internal diameter telescopes.
2. Accurate Focusing: This mask eliminate guesswork during focusing, overcome limitations of visual conditions, and allow you to quickly and easily achieve best focus for your telescope.
3. Secure Clamping: Focusing mask can easily clamp the telescope securely to prevent sliding, maintain proper centering, and ensure compatibility with a wider range of telescopes.
4. Diffraction Pattern: The fishbone focusing pattern acts as a set of artificial diffraction gratings. When light passes through the fishbone board, it diffracts in three different directions, forming three pairs of lines. By adjusting the focus length, the light pattern moves until the three sets of lines align, indicating the correct focus.
5. Lightweight and Strong: Telescope focus mask is made of lightweight and sturdy aluminum alloy material, the design helps maintain balance, is easy to carry, and will not damage the telescope.
