My medium focal length, high contrast APO setup. A dream scope, for sure.

The Thomas M. Back designed APM 130/780 APO Refractor.

According to OPT, where I purchased the scope:

"The superb optics in this APM 130mm f/6 Super APO triplet are made by LZOS in Russia. The new CNC LW II tube assembly is made in Germany with loving care, and the internal baffles are matched. Unbeatable 3.5" Feathertouch focuser is fully rotatable and produces zero image shift."
