I have obtained a VERY old Maksutov with NO defining information on the scope as to focal length/"f"#, diameter, etc. It looks to be a 5"(about 127mm) mirror. The tube is 6&1/8"(154mm) outside diameter. The TUBE is 324mm(12 & 3/4") long. The diagonal attaches w/ a set screw, and takes 1.25" eyepieces. The base is a single-arm type(with a variable-speed motor in the base) alt-az mount.
The only info on the unit is ATOMIC LABORATORIES INC, Subsidiary of CENCO instruments corp. Catalog # 87716, volt 110ac, 50-60 cycle. I would like to find out the focal length, actual diameter, and f-ratio. The scope gives very good views, although not very wide field. Thanks for any help. Walter.
