APM/TMB/LZOS 80/600 Super-Apo

APM sold two versions of the 80 mm APO: the 80/480 and the 80/600. These are nifty little APOs with very good performance. They have a splendid Feathertouch focuser. In this image, the refractor is held by two craddlerings on a short Losmandy dovetailplate. This has been changed in the mean time to increase the spacing of the rings, providing better support.
