This is the deluxe model with a 1/20 wave, 96% dielectric coated
mirror. Per APM (p.v. 1/26.5 Lambda, RMS 1/137.5 Lambda). Threaded
for 48mm filters the diagonal and adapter both have nonmarring brass
compression rings. One year old and except for some setscrew marks
on the barrel, it is in excellent shape. Optically as good as a
Maxbright, but aesthetically built like a Russian T-34 Tank.
