I have made this Binoscope without making.
Q1: Where is the base mount or the framework of the Binoscope?
A1: Nothing!
Q2: Where is the Binoscope Body?
A2: Nothing!
Just put a pair of OTAs on the Center Mount and it acts as a Binoscope.
Hence, a pair of the EMS-UXL and a Center Mount made a Binoscope.
双眼望遠鏡は「作らずに作れます。」
中軸架台とEMSがあれば。^^; もちろん鏡筒が2本要りますけどね。
