About Sky-Watcher S11670

The Sky-Watcher EQ5P 11SCT is a Schmidt-Cassegrain Telescope. As a single component, the 11" optical tube is easily manageable as is the mount and tripod. Compared to a 10", 11", or 12" one piece, fork-mounted SCT design, the SW 11" is vastly more manageable to lift, set up and transport. A perfect example of why the equatorial mount has the advantage in enabling individual amateur astronomers to comfortably operate larger aperture telescopes.

If you have ever lifted a large one-piece fork-mounted SCT a half dozen times, or so, you will appreciate the difference. Incredible indeed are the highly resolved images to be viewed or photographed through this advanced observatory-class instrument. You will see a lot more in a SW 11" SCT compared to smaller 8" and even 10" telescopes at limiting visual magnitude. Diffuse emission nebulae in the summer sky like the Lagoon (M8), Trifid (M20) and Swan (M17); the stunning globular star clusters M13 and M92 in Constellation Hercules; the Rosette Nebula in Monoceros shows the discernable pattern of a blooming rose; the awesome winter sky's Great Orion Nebula (M42) in Constellation Orion and the local galaxy group companion the Andromeda Galaxy (M31) in Constellation Andromeda, to name a very few, will appear more spectacular, brilliant and wider in extension as seen in a SW 11" SCT.

The Moon almost takes on a feeling of viewing in 3D. Subtle discontinuities, ripples and festoons in Jupiter's bands present themselves in bold relief against surrounding Jovian landscape. Saturn's inner crepe-ring is clearly discernable. Martian polar-regions and surface mottling is presented with clarity impossible to experience with a smaller aperture telescope. In addition to the objects listed above, challenging phenomenon for an 8" and perhaps a 10" aperture now come into their own with the SW 11": the planetary nebula the Crab (M1), a supernova remnant, requires a least a10" aperture to truly begin to appreciate the several subtle, gaseous filamentary structures, but it will look even better in an 11".

M15 a globular star cluster challenging to view in smaller telescopes will resolve almost in its entirety into thousands of stars. M101 is a very beautiful faint spiral galaxy often difficult to see. With the SW 11" light-gathering power, it is a lot easier to find than M27, the Dumbell, or Hourglass Nebula in constellation Vulpecula resembles an hour glass in a large telescope. M51, the Whirlpool Galaxy, displays remarkable greater structural detail in an 11" aperture vs. an 8"or even a 10" diameter telescope. There is no question you will find the incremental resolving power of a SW 11" SCT impressive.

Sky-Watcher S11670 Features

  • Telescope Tube Attachment Hardware: The optical tube comes with attachment hardware that allows it to be securely fastened to the SW EQ5 PRO mount. These quick-release tube rings are cast-aluminum, power coated white
  • The Sky-Watcher EQ5 PRO equatorial mount is a premium-grade observing platform utilizing quality mechanical and electronic component materials throughout
  • Mechanical Surface Controls: Thumb-locks are provided in RA and Dec. to allow swift manual orientation of the optical tube assembly
  • Rock-Solid Tripod and Payload: Every SW EQ5 PRO mount includes a metal tripod commensurate in rigidity and load-bearing capacity to the EQ5 PRO mount itself
  • Computer Operation: Sky-Watcher GO-TO telescope models include the revolutionary SynScan Computer Controller. The SynScan's remote hand-controller plugs into SW motor-control panel
  • Motor Speeds, Tracking Modes and Alignment Types: The operating versatility of SynScan provides guiding speeds of .25x, .5x, .75x and 1x
  • Astrophotography: Sky imagers will appreciate the auto-guider port for guiding using a PC via the RS-232 port (if the software supports ASCOM)
  • Database: The SynScan computer includes a celestial database of over 30,000 objects, including all the crowd pleasers like planets, the Moon, Messier objects and interesting double stars
  • Portability: Equatorial mounts, like the Sky-Watcher EQ5 PRO, also offer great convenience to observers seeking portable equipment that disassembles into manageable components that can be easily lifted and carried
  • Stability and Balance: The equatorial mount is renown for stability and ease-of-use in achieving mechanical balance of the optical tube and mount
  • Computer Operation: The SW EQ5 PRO Series offers manual or computerized operation. The revolutionary SW SynScan computer works seamlessly with the SW EQ5 PRO mount to facilitate effortless, automatic tracking and object location of over 13,000-objects
