About the Sky-Watcher BK 12" Collapsible Dobsonian Telescope...

A collapsible truss-tube Dobsonian Sky-Watcher Telescope design that requires no re-assembly - the ultimate convenience!

 

SkyWatcher does it again. An old favorite - the Sky-Watcher BK 12" Collapsible Dobsonian Telescope - gets a complete facelift with new features and upgraded components!

 

The venerable Dobsonian Sky-Watcher Telescope reflector design has recently undergone some important upgrades and improvements: SkyWatcher is pleased to introduce the all-new Collapsible Dobsonian complete with Crayford focuser - the ultimate in large aperture portability and performance.

 

This elegant truss tube design of the Sky-Watcher BK 12" Collapsible Dobsonian Telescope was carefully engineered to combine ease of use, extreme portability and consistent performance in an affordable package. Unlike other truss tube designs, the Sky-Watcher Telescope Collapsible Dobsonian does not need to be disassembled between uses. It transports as two compact pieces that can be assembled and ready to use in just seconds! It is easy to collimate once set up, and it holds its collimation throughout the evening!

 

The bearing system has been redesigned as well. The new Sky-Watcher BK 12" Collapsible Dobsonian Telescope features buttery smooth azimuth bearings. Even the largest model can be rotated with just the push of a finger. Like traditional Dobsonians, the new Collapsible Dobsonians feature SkyWatcher'''s patented tension adjustment control on the altitude bearings. This eliminates the need and added cost of clumsy counterweight systems to balance the Sky-Watcher Telescope.

 

To top it off, all of the new Sky-Watcher BK 12" Collapsible Dobsonian Telescope is shipping with ultra smooth Crayford focusers. 90 degree finderscope is also available. Don''t forget, we carry plenty of Sky-Watcher Accessories, too! Look for Sky-Watcher Telescope Eyepieces and Sky-Watcher Telescope Filters for visual observers!
