At almost 10″ in diameter, this is the largest dobsonian in the library. This venerable telescope (made in Canada!) is mounted on a solid metal base and adjusts easily. It can fit in the back seat of a car, fully assembled, which is quite unusual for a large Dob. It’s a really good telescope, with stars showing nice and crisp. The optical finderscope is somewhat awkward to use since the tube is relatively short.
