SkyWatcher S11700 8-Inch Collapsible Newtonian Reflector Telescope

SkyWatcher 8" Collapsible Dob Brand NewIncludes Limited Two Year Warranty The SkyWatcher 8-Inch Collapsible Dob Telescope features a large-aperture, short focal-length, Newtonian reflector. Sky-Watcher's optical tube design utilizes their proprietary truss support system. That system allows the optical tube's front and back tubes to collapse together, aligning on the truss support rods, and locking down for secure transport. An 8x50mm right angle optical viewfinder provides both magnification and light gathering to help narrow your search for those elusive fuzzies while star-hopping. Some prominent deep-space objects seen well in an 8" SW DOB are the Lagoon (M8), Trifid (M20), and Swan (M17) nebulae, the globular star clusters M13 and M92 in Hercules, the Great Orion Nebula (M42) and our local galaxy group companion, the Andromeda Galaxy (M31), and many more. The standard, backlash-free, 2" Crayford Focuser insures ultra smooth focusing adjustments. 8-Inch Collapsible Dob Features: 8 Inch Aperture (203mm) Focal Length: 1200mm, f/6 Focal Ratio 8?50 Finderscope Truss-support System Dobsonian Solid Rocker-mount 2" Single-Speed Crayford Focuser Teflon Bearings Tension Clutch Collapsible Tube Design Specifications: .boldTbl{ font-weight: bold;}.specs td, table.specs th {padding: 4px 10px;}Optical Design :Newtonian ReflectorAperture (mm) :200mm (8 in)Focal Length (mm) :1200 mm (47 in)Focal Ratio :f/6Eyepiece Barrel Diameter :1.25"Maximum Useful Magnification :472xLowest Useful Magnification :29xLimiting Stellar Magnitude :14Finderscope :8x50Finderscope :RA ViewfinderMount Type :DobsonianFocuser Size :2"Focuser Speed :Single SpeedEyepieces :4-element PlosslEyepieces 25mm Power :48xEyepieces 10mm Power :120xOptical Tube Weight :24.2 lbs (11 kg)Optical Coatings :Aluminum with Multi OvercoatsLight-Gathering Power Compared to Human Eye : 816x
