20mm Orion HighLight Plossl Telescope Eyepiece Reviews

20mm Orion HighLight Plossl Telescope Eyepiece Feature

  • This 20mm HighLight 1.25" eyepiece appeals to skywatchers who want an extra performance edge thanks to its fully multi-coated optics
  • A great telescope eyepiece for taking in medium magnification views of the Moon, planets, and brighter deep space curiosities
  • Fully multi-coated 4-element optics for the highest possible light transmission and better contrast
  • Offers a generous 52 degrees field of view and crisp, sharp images with moderate magnification
  • Threaded for use with 1.25" eyepiece filters
Orion HighLight Plossls are our exclusive, premium line of 1.25" Plossl eyepieces with some noteworthy enhancements. HighLight eyepieces offer a generous 52-deg field of view and crisp, sharp images. The HighLights' 4-element optics are fully multi-coated -- every air-to-glass lens surface is multi-layer coated for the highest possible light transmission and better contrast. The lens edges are blackened for additional contrast enhancement. The machined aluminum housings of the HighLight Plossls sport a distinctive anodized finish, with grip traction knurled right into the metal. Supple rubber eyeguards shield out extraneous light and fold down for eyeglass wearers. The barrels of HighLight Plossls are precision-machined to a tolerance of +/- 0.05mm from the nominal specification, so you can be sure of a great fit in your diagonal or focuser. And of course they are internally threaded to accept filters.

Tele Vue Plossl 40mm - 1.25" Eyepiece EPL-400

Tele Vue Plossl 40mm - 1.25" Eyepiece EPL-400 Reviews


Other Picture


Tele Vue Plossl 40mm - 1.25" Eyepiece EPL-400 Feature

  • Focal Length 40mm
  • Barrel Size 1.25"
  • # of Elements 4
  • Apparent FOV 43 degrees
  • Weight - .41lbs

Diffraction limited "on-axis" performance is a given. Using more expensive high-index glasses to reduce astigmatism and lateral color at the field's edge, Tele Vue Plossls deliver sharper images than any other brand of 4 or 5 element "Plossl" or Orthoscopic designs. The faster the focal ratio of your telescope, the greater your visual reward for using Tele Vue eyepieces. Tele Vue Plossls feature full multicoatings for greatest light transmission and contrast. Blackened lens edges and internal anti-reflection threads tweak the last bit of contrast for maximum image detail. The sharper field focuses faint star light into perceptible points and allows those with undriven mounts to gaze longer before repositioning the image.

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 Reviews

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
