It's only a 15cm or 6" f:10 Maksutov telescope but it looks and feels like a much bigger instrument.
All metal, no plastic and a lot of beautiful glass made in the 1970's..
The Mk63 sits on an equatorial wedge with a motor and controller on the RA. It runs smooth.
Nice feature is the small Maksutov Guiding Scope.
The complete set with original adapters makes it easy to attach a camera to the scope.
