Mount the Sky-Watcher 14" GoTo Collapsible Dobsonian Optical Tube Assembly on a compatible base to observe night sky treasures such as planets and the moon, nebulae, star clusters, galaxies, and much more. Its large parabolic borosilicate primary mirror is treated with a combination of quartz, titanium, and silicon dioxide to bring its reflectivity to over 94%, with a secondary mirror obstruction of just 6% by area. The OTA's truss design allows it to retract to just 38.5" long for easier transport and storage, and then extend to 60" for observation.
The large 14" aperture draws in copious amounts of light to resolve awe-inspiring deep-sky objects like wispy nebulae and galaxies, while also revealing incredible details of the lunar surface and planetary features. The 2" focuser will accept larger eyepieces so users can enjoy a truly immersive visual experience and will ensure larger imaging sensors are completely covered. For convenience, Sky-Watcher includes a reducer adapter that will allow you to use more common 1.25" eyepieces.
- Large 14" (356mm) aperture, long 1650mm focal length
- Collapsible truss system saves space during transport and storage, measuring 38.5" when trusses are retracted and extending to 60" when set up
- Borosilicate parabolic primary mirror
- Quartz, titanium, and silicon dioxide mirror coatings bring the reflectivity to 94%
- Resolution: 0.33 arcsec (Dawes Limit), 0.39 arcsec (Rayleigh Limit)
- 83mm secondary diameter mirror; Obstruction: 23% by diameter, 5% by area
- 64" eyepiece height when aimed directly overhead at the zenith
- 16.5625"outside tube diameter
- Crayford-style is much more precise than the traditional rack-and-pinion
- Tension control system eliminates gears, resulting in zero backlash for tack-sharp focus on dim objects or objects, like binary stars, that are close together
- 2" diameter holder allows the use of larger eyepieces and imaging systems that provide a wide field of view and long eye relief to make viewing dim and small deep-sky objects more comfortable
