About Baader Planetarium BBHS Mirror Star Diagonal

FEATURED REVIEWS

Perfect, like all Baader equipment.

By ALEXANDER T.

Solid, clear, obvious quality jump from cheaper brands.

Explore the exceptional quality of the Baader 2" BBHS Mirror Star Diagonal with 2" ClickLock Clamp. This advanced optical device, featuring a broadband hardsilver (BBHS) coating with a dielectric protective overcoat, elevates your viewing experience into the silver category. The upgraded black housing now incorporates a 2" ClickLock clamp for secure and easy handling.

The heart of this star diagonal is the Sitall glass ceramic mirror, now enhanced with our all-new protected hard-silver coating. This innovative combination ensures full-spectrum reflection between 400 and 2000 nm, eliminating light loss and providing superior clarity. This makes it an ideal choice for those seeking the best product or those working in the IR-passband.

Historically, silver coatings have been favored for their high reflectivity for over 300 years. However, the challenge has always been the unprotected silver's susceptibility to aging and tarnishing. Our solution is a new, proprietary, and weatherproof coating of hardened silver. This coating, in combination with the temperature-resistant Sitall, delivers an unparalleled viewing experience. You'll experience no light loss and a total absence of haze, resulting in a crystal-clear image.

Experience the difference for yourself and discover why our hard-silver BBHS-star-diagonals are considered the absolute best in star diagonals. This product is a testament to our commitment to innovation and quality, offering you the ultimate in precision and performance.
