COLLAPSIBLE DOBSON 12''

The Sky-Watcher 12" Collapsible Dobsonian brings a substantial 305 mm aperture to a portable, truss-tube design. The patented collapsible tube shrinks for storage and transport, then reliably holds collimation when reopened, so no disassembly is needed between sessions and the scope separates into manageable pieces. At 1500 mm focal length and f/5, this large reflector reveals faint deep-sky objects with impressive brightness and detail.
