The 20" telescope was purchased from Obsession Telescopes, which is owned and operated by Dave Kriege, the well-known Dobsonian telescope manufacturer and author, in Lake Mills, Wisconsin.  The telescope is a Newtonian reflector with a 20 inch primary mirror and a 3.1 inch secondary (diagonal). The mount is a Dobsonian, which was invented by the amateur astronomer John Dobson in the late1950s and is particularly useful for large portable telescopes. This particular Obsession telescope came with Argo Novis Digital Setting Circles (arrived defective and had to be repaired) and a ServoCAT GoTo computerized drive .

Telescope rocker box and mirror box ready for transport with the wheelbarrow handles.
