2″ BBHS Star Diagonal with 2″ ClickLock Terminal
The Baader 2″ BBHS Star Diagonal features the highest quality mirror diagonal design with BBHS (Broadband Hardsilver) coating for optimal reflectance across a broad spectral range of 390 to 2000nm. This star diagonal provides superior brilliance compared to standard dielectric-coated diagonals. The unique BBHS coating, combined with a dielectric protective overcoating, ensures the brightest and clearest views for all observers. It’s equipped with a T-2 BBHS-Sitall zenith mirror on both sides, with T-2 photo threads, offering secure, high-quality optical connections.
Key Features:
- BBHS Coating: Broadband Hardsilver (BBHS) coating with dielectric protective overcoating, offering the highest reflectance and brilliance across most of the visible and infrared spectrum (390-2000nm).
- Optimal Reflectance: The BBHS coating outperforms standard dielectric coatings, providing enhanced brightness and clarity.
- ClickLock Clamping System: Equipped with Baader’s ClickLock system for quick and secure attachment of eyepieces and cameras with a firm hold, preventing slippage.
- Zenith Mirrors: T-2 BBHS-Sitall zenith mirrors on both sides ensure sharp, high-contrast images.
- Wide Compatibility: The diagonal is compatible with M48, M55, and 2″ (50.8mm) threaded connections, making it versatile for use with many different telescopes and accessories.
- 90° Deflection Angle: Offers a comfortable viewing position with a 90° deflection angle and an erect image orientation (mirror inverted).
- Clear Aperture: The 47.5mm clear aperture ensures maximum light transmission and field of view, ideal for both visual and photographic applications.
- Optical Length: The optical length of the diagonal is 112mm, providing optimal focus and ease of use.
