About
Stellarvue's most advanced diagonal, designed by Vic Maris over two years: a thick oversized mirror polished to 1/10 wave in low-expansion quartz rather than the usual BK7, dielectric coated for 99 percent reflectivity, in a body CNC-machined from solid aluminium in the USA. A four-point adjustment lets every unit be dialled into perfect alignment and a five-point cushion system prevents pinching in any climate. This version adds a twist lock, a compression-ring eyepiece tube and a bevelled insert tube that seats better in the focuser.
