one of the worldbest 80 mm Planetary Refractors with zeiss Optics. Semiapo here means a colorcorrection similar to todays fast ED Apos, just with a superlative perfect spherical correction as you never find in any fast douplet ed apo on the market. The tube is a ATM project very nicely made by using the original Zeiss M52 focuser with sliding drawtube and 2" eyepieceholder, set of tuberings and a selfmade 80 mm finder.
