Vixen ED103S Telescope with Dual Speed Focuser and Sphinx SXW Mount Feature

• ED103S with Vixen's Dual Speed Focuser
• ED Apochramatic Refractor with fantastic contrast
• Sphinx SXW Mount with the built in star chart STAR BOOK Hand Controller
• Includes NLV25mm Eyepiece, Flip Mirro, Finder Scope
• Vixen's universal Dovetail System to easily interchange scopes.

The Vixen ED103S is an apochromatic refractor, with fantastic contrast and 4" aperture, sufficient for viewing most of the planets and many stars.  With its ED glass elements, chromatic aberration has been reduced to nearly undetectable levels, permitting a much more practical use of the higher magnifications quoted in the specifications than when seemingly identical in a normal achromatic refractor.  Vixen’s ED Glass has brought refractors back to the forefront of premium telescope choices, to compete with the 8" and larger ubiquitous Schmidt-Cassegrains that, while bringing in enormous quantities of light, simply cannot compare to the contrast of the apochromatic refractor. The included flip-mirror adapter allows either 90° or straight-through observing.  With an eyepiece upon each end of the flip-mirror, you can quickly switch between the two as the declination of your object of interest changes its location in the sky. The SPHINX equatorial mount and STARBOOK controller have been intelligently engineered for high-speed automatic location of celestial objects. It is now possible to explore the beauty of the night sky with greater ease and stability. The SPHINX comes standard with built in motors and the world's first star chart go-to controller, STARBOOK, with a large full color LCD display.

Orion Long 2" Adapter for Crayford-Type Telescope Focuser

Orion Long 2" Adapter for Crayford-Type Telescope Focuser Reviews

Other Picture

Orion Long 2" Adapter for Crayford-Type Telescope Focuser Feature

• Adapter designed for use with the Orion 2" single speed Crayford focuser to allow focus to be achieved with some reflector telescope optical tubes
• Provides extra height needed when single-speed Crayford focuser is used with Orion 203mm f/4.9 and 254mm f/4.7 reflector optical tubes
• Adapter is not required for use of single-speed Crayford focuser on Orion Dobsonian telescopes
• Allows visual use of eyepieces with specialty focuser and some mounted reflector telescope tubes
• Made of anodized aluminum

This extension adapter is designed for use with the Orion 2" Crayford-type focuser (#13039). The adapter provides the extra height needed when the focuser is used with Orion 203mm f/4.9 and 254mm f/4.7 reflectors. The adapter is not required on Orion Dobsonians.

Skywatcher 10" Dobsonian 1200mm Focal Length (f/5.0) with 2" Crayford Style Focuser, 1.25" adaptor, 10mm & 25mm Plossl Eyepieces, 8x50 VF, & Rocker Mount Feature

• The Sky-Watcher 10" DOB utilizes quality components throughout
• The polishing process for primary and diagonal mirror yields smooth mirror surfaces ensuring good contrast and properly corrected optics show minimum alterations to the optical wave-front
• The standard-equipment backlash-free 2" Crayford Focuser insures ultra smooth focusing adjustments
• An 8x50mm Right Angle optical viewfinder provides both magnification and light gathering to help narrow your search for those elusive fuzzies when star-hopping
• To ensure mechanical ease-of-use, SW uses a high-performance Teflon bearing system in both axes combined with tension adjustment in altitude to facilitate setting the appropriate amount of friction

The Skywatcher 10" DOB is an very satisfying telescope to own, an instrument that will provide a lifetime of continuing exploration of the heavens. This telescope provides all the capability and value you are seeking in a large aperture telescope. Skywatcher'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. This one piece, low-hassle OTA design is mechanically simple and results in a large aperture telescope that can be reasonably handled and transported by one individual. This innovation gives Skywatcher users tremendous functional ease-of-transportability. With this telescope you have tremendous light gathering power. Prominent deep-space objects seen well in an 8" SW DOB, such as 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 awesome winter sky's Great Orion Nebula (M42) in Constellation Orion and the enormous 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 in a SW 10" DOB. Many challenging objects for an 8" aperture now come into their own with the SW 10" DOB: the planetary nebula the Crab (M1), a supernova remnant, requires a 10" aperture t
