I'm selling my TMB 100/800 f/8 apochromatic refractor (serial #94) in
German CNC tube for $2,675 including S/H. Accessories include: 4"
tube rings, quick change finder bracket, 2" to 1.25" compression ring
adapters, 100mm extension tube, interferometric report (PTV .127,
RMS .017, and Strehl ratio .988), Mizar plate for attaching the rings
to a APM Giro2 altaz mount, and aluminum carrying case. I purchased
this scope directly from Thomas Back last January. See Dave
Novoselsky's review on Cloudynights for pictures. If you are
interested or have any questions, please feel free to e-mail me.
