BAADER 2" CLICKLOCK BBHS ASTRO-AMICI PRISM

The Baader 2" Clicklock BHHS Astro-Amici Prism Diagonal is an ultra high quality diagonal specifically made for highest-magnification astronomical use and manufactured to the original Zeiss standards.

Unlike low cost roof prisms, the Amici roof prism has extremely accurate roof edges and surfaces, giving it unparalleled sharpness at high magnifications.

Utilizing BaK-4 glass and with Baader's exclusive Broad Band Hard Silver coating, this diagonal has 99% reflectivity across a staggering 390 - 2000nm spectral bandpass. This extended NIR range allows use with modern IR-sensitive CMOS planetary cameras with exceptional clarity.

With a well trained eye, the BBHS coating provides in ultra-high contrast and richer colours on planets such as Jupiter, Mars and even the moon. The silver produces absolutely zero scattered light, which extra dielectric coatings protect it for a lifetime of use.

Being a prism-type diagonal, it is not recommended for use with refractors faster than f/6 - f/7.

In conjunction with the strong and lightweight magnesium body, the BBHS coating remains at thermal equilibrium in all situations and supplies a sharp, stable and calm image unlike any other diagonal.

The Baader 2" Clicklock clamp allows extremely precise and even securing of heavy eyepieces and accessories without introducing any tilt or offset. The removable 2" nosepiece is threaded for 2" filters and includes safety kerfs to prevent the diagonal from accidentally slipping. The prism housing includes an S58 dovetail connection and M55 threads.
