Difficult to Impossible to Make Usable

Cannot caliber or collimate to make telescope usable. Instructions are vague and/or non-existent. Found Youtube video showing how to collimate using a laser collimator which required another purchase to make usable. Still not working. Currently using as very expensive dish towel rack.

Excellent scope

By GABRIEL M.

Easy to collapse and transport. Assembly was a breeze.

The Sky-Watcher Flextube 300P Collapsible 12" makes everything in deep-space appears brighter and wider. Many of the more challenging to resolve objects in smaller diameter telescopes now reveal their essential structure. Objects just within the threshold of a 10" aperture now appear more prominent and may be worth dwelling upon for extended periods. Comet hunters will delight in the fainter magnitudes that are possible to discern in the SW 12" DOB. Here at last is a telescope within the threshold to tackle elusive deep-space gems like the Horsehead Nebula in Constellation Orion.

Located in Constellation Perseus, M76, is a very faint nebula of 11th magnitude. The SW 12" will capture this baby like you want to see it. M97, a planetary nebula in Ursa Major is very faint, but as a serious amateur you will want to see it. No worries, the SW 12" DOB will fulfill your quest. M61, a spiral galaxy in Constellation Virgo, will reveal spiral arms as you would hope to see them, but you will need a SW 12" telescope to resolve them well. The list goes on and you will delight in planning your own journey of exploration. The incremental resolving power of the SW 12" aperture is beyond just being impressive, it's within amateur astronomy's super aperture threshold where the lucky observer is able to resolve well, many, many objects that smaller telescopes just don't have the horsepower to detail satisfactorily because they can't pull in enough light. Again, Sky-Watcher's compact, collapsible optical tube design makes this super aperture 12" DOB a far more practical decision to purchase.

Sky-Watcher Flextube Dob Features

  • An 8x50mm Right Angle optical viewfinder provides both magnification and light-gathering to help narrow your search for those elusive fuzzies when star-hopping
  • The standard-equipment backlash-free 2" Crayford Focuser insures ultra smooth focusing adjustments
  • To ensure mechanical ease-of-use, Sky-Watcher uses a high performance Teflon bearing system in both axes combined with tension adjustment in altitude to facilitate setting the appropriate amount of friction, assuring smooth vertical and horizontal manual movement
  • Sky-Watcher's Teflon bearing system is preferable to the use of ball-bearings. Ball-bearings make unintended movement of the optical tube more difficult to control
  • At low power, deep-space objects leisurely drift through the field of the SW 12" DOB, so constant mechanical adjustment of the telescope's orientation isn't needed to keep objects in the field of view
  • Sky-Watcher's revolutionary truss-support concept allows the optical tube's front and back cells to collapse together, aligning on the truss support rods which can then be locked down for easy and secure telescope transport
  • The Sky-Watcher 12" DOB utilizes quality components throughout
  • The mechanical and structural components of the OTA exhibit rigid construction and outstanding stability
