This is an ugly orange Konusuper 120.
Achromatic objective lens 120mm (4.7") in diameter, with a focal length
of 1000mm, giving f/8.3. Mods include a 9X50 Orion finder, a CG-5
mount with one axis drive (only good for general observing, not photography),
a Moonlite dual-rate focuser and 2-inch diagonal. Its not an APO, but
I've enjoyed many hours of observing with this.
