About
A 100 mm f/5.5 sextuplet fully air-spaced APO astrograph with two ED elements, three in front and three at the back, self-flattening so no back focus has to be calculated. It carries a 3.4-inch rack-and-pinion focuser with 1:10 fine adjustment and a 360-degree rotator, and ships with a stepped four-piece M86-to-M48 adapter set.
