Padded blue cordura/nylon case as sold by Orion. Holds the optical tube/fork arm assembly; a thick layer of dense foam trapped between the outside fabric and the lining provides good, yet lightweight protection. The case has a zippered closure, a carrying handle, a large (11x12x2.5") external cargo pocket, and a 2nd external flat pocket. I've been using it on a Celestar 8, but Orion lists the same item for the Ultima 2000.
