Cosmos Mariner (or simply "Mariner") is my current telescope, a homebuilt 22" f/5 Dobsonian. The links below will outline pertinent information about the design, construction and features of the telescope.

Note that the construction notes are not sequential! Many of the building phases were interleaved (like the truss, the bearings, and finding the balance point to position the bearings). However for this recounting, I found it convenient to document everything by superstructure.
