Apochromatic refractors produce the sharpest and highest quality images of all telescope systems thanks to their shadow-free, textbook-like diffraction pattern. The Skywatcher high-end Evostar 72ED Apo refractor contains a doublet lens with a lens made of particularly low-index ED glass. The highest quality glass was also used for the crown glass element. Each glass-air surface of the optics has been given an exotic, metallic anti-reflection coating to achieve a high, maximum light transmission of 99.5%! The groundbreaking Skywatcher “Metallic High-Transmission Coating” (MHC) is the highest quality optical lens coating in its class. (Please note that the Evostar 72ED Apo contains a different objective lens glass combination than the Evostar 80ED / 100ED and 120ED models) Attention Star diagonal and eyepiece are not included!Scope of delivery: 72 mm F/420 mm optical tube/transport length 420 mm dual speed focuser 2″ with 11:1 reduction tube clamp and Vixen/Skywatcher style dovetail aluminum carrying case with additional shapes for accessories!Power supply and batteries are included not included in the delivery!
