– 2″ BBHS Sitall star diagonal with 2″ ClickLock clamp and black
Housing
– Astro Sitall mirror material (glass ceramic with zero
coefficient of expansion), 1/10 lambda surface finish
– Largest reflectivity over the largest spectral range of 390
up to 2000 nm
– BBHS = broadband hard silver coating with dielectric
protection fee
– ideal for observation and photography with the highest brilliance, even in
infrared spectrum
– Evidence shows that silver offers in connection with the
temperature-resistant Sitall the absolute best viewing experience
complete absence of stray light.
