Review of Short Phrases and Links

    This Review contains major "Eyepieces"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. Eyepieces are angled at 45, offering excellent versatility for both terrestrial and astronomical viewing. (Web site)
  2. Eyepieces are interchangeable and many different eyepieces can be inserted with different degrees of magnification. (Web site)
  3. Eyepieces are available in a wide range of optical configurations, barrel diameters, and focal lengths. (Web site)
  4. Eyepieces are angled at 90 making them ideal for high-angle astronomical viewing. (Web site)
  5. Eyepieces are denoted according to their magnification, whether they are wide angle (WW or WA) or variable zoom eg. (Web site)

Heavy

  1. The trade-off is that these eyepieces are usually more expensive, won't fit in some telescopes, and may be heavy enough to tip the telescope.

Center

  1. Most modern binoculars have one focus wheel in the center that moves both eyepieces, and then one eyepiece has an independent focus.

Standard

  1. Note: These eyepieces are not interchangeable with standard 1.25″ telescope eyepieces.

Significant

  1. Eyepieces and other accessories, however, are probably worth the risk if the price difference is significant. (Web site)

Perfect

  1. Perfect for cleaning binocular lenses, small aperture spotting scopes and telescopes, eyepieces, and other optical items.

Special

  1. At one time, eyepieces were available in a wide spectrum of magnifications ranging from 6.3x to 25x and sometimes even higher for special applications. (Web site)

Collection

  1. Modern Barlows are high quality and a good choice for expanding your collection of eyepieces. (Web site)
  2. A collection of different types of eyepieces. (Web site)

Astrophotography

  1. Astronomy related information, including telescopes, eyepieces, and astrophotography and forums.

Amateur Telescopes

  1. In the last 30 years or so, 1.25″ has become the standard for amateur telescopes, although large telescopes may take 2″ eyepieces.

Interpupillary

  1. Interpupillary Distance: Distance between the two eyepieces. (Web site)

Typical Eyepieces

  1. Typical eyepieces have field of view ranging from 40° to 65° or more.

Switching Eyepieces

  1. Thus, telescopes are normally indicated by the diameters of their objectives rather than by the magnification which can be changed by switching eyepieces.
  2. This is desirable but not necessary while switching eyepieces when looking at the same object.

Several Eyepieces

  1. Most telescopes come with several eyepieces and you can buy more separately. (Web site)

Large Apparent Fields

  1. These eyepieces are well corrected, with very large apparent fields of view, of 84 degrees. (Web site)

Low Power Eyepieces

  1. Use only very low power eyepieces when viewing this object with a scope. (Web site)

Lanthanum Lv Eyepieces

  1. Vixen is particularly noted for refractors with fluorite doublets, and for Lanthanum LV eyepieces. (Web site)

Extra Eyepieces

  1. Extra eyepieces will allow varying levels of fixed power, wider fields of view and other factors.

Three Eyepieces

  1. It comes with three eyepieces: quality 20mm, 8mm lens gives you a magnification of 40x and 100x. (Web site)

Huygenian Eyepieces

  1. Even though neither of the lenses is an achromat, Huygenian eyepieces do an excellent job of correcting lateral color. (Web site)

Plossl Eyepieces

  1. Plossl eyepieces have a four-element or five-element design, with a 50-degree field of view.

Orthoscopic Eyepieces

  1. Orthoscopic eyepieces can range from $50 to $100 each. (Web site)

Oculars

  1. Such systems may be divided into four classes: telescopes, oculars (eyepieces), photographic objectives, and enlarging lenses. (Web site)

Huygens Eyepieces

  1. A Huygens eyepieces consist of two plano-convex lenses with the plane sides towards the eye separated by an air gap. (Web site)
  2. The conclusions drawn from the data are: (1) Telescopes with Galilean eyepieces have a smaller CA than those with Keplerian or Huygens eyepieces. (Web site)

Ramsden Eyepieces

  1. Even though neither of the lenses is an achromat, Ramsden eyepieces do an excellent job of correcting lateral color. (Web site)

Barlow

  1. Thus, with these eyepieces, for a given magnification there will be greater eye relief with a barlow than without.

Barlow Lens

  1. Complete with two eyepieces, barlow lens, 6x30 optical finder scope and solar observation screen.

Kellner Eyepieces

  1. As well, Plössl, Orthoscopic, and Kellner eyepieces, for example, can be made with many different types of glass. (Web site)

Compensating Eyepieces

  1. Because this defect is also found in higher magnification achromats, compensating eyepieces are frequently used for such objectives, too. (Web site)
  2. As a result, compensating eyepieces have build-in lateral chromatic error and are not, in themselves, perfectly corrected. (Web site)
  3. To remedy this, manufacturers produce compensating eyepieces that introduce an equal, but opposite, chromatic error in the lens elements. (Web site)

Different Eyepieces

  1. You don't have to fumble for different eyepieces to find the perfect one to use at a given moment. (Web site)

Telescope Eyepieces

  1. Meade, Celestron, and Zhumell are but a few of the high quality, name-brand telescopes and telescope eyepieces you'll find on our site.
  2. Second, choose a spotting scope model that uses interchangeable telescope eyepieces, preferably 1.25" telescope eyepieces. (Web site)

Tube

  1. Tube rings, tube ring mounting plate, finder scope, and eyepieces sold separately.

Number

  1. This doubles the number of eyepieces in your collection. (Web site)

Purchase

  1. Make sure that the eyepiece holder in your telescope can support the eyepieces you wish to purchase. (Web site)

Models

  1. Hand held models will be 5x to 7x but with very large prism sets combined with eyepieces designed to give generous eye relief. (Web site)

Size

  1. The size, almost always.965", 1.25" or 2" refers to the barrel diameter of the eyepieces it accepts. (Web site)
  2. Beyond that, the types of eyepieces available in.965" size is very limited, and they tend to be of lower quality.

Construction

  1. The Hyperplane and Compensating eyepieces, Figure 14, are similar in construction to the Huygenian eyepiece, except that the eyelens is a doublet.

Detail

  1. Zoom eyepieces allow birders to scan at low power, then crank up the magnification to get the most detail. (Web site)

Details

  1. Astro-Tom.com Eyepiece Article, a list of eyepieces with some details of their construction. (Web site)

Sets

  1. Invest in the multiple sets of filters and eyepieces, you wont be sorry.

Right

  1. Also, the drawtube accepts standard 1.25" eyepieces - that's right, no trashy.965" eyepeices.

Situation

  1. Eyepieces: Eyepieces help with your magnification depending on the type you prefer in any given situation.

Addition

  1. The addition of an accessory tray can hold your eyepieces and other small accessories.
  2. In addition, all eyepieces have protective eyepiece covers.
  3. Kellner eyepieces are a fairly aberration-free improvement on the Ramsden with the addition of an achromat for the eyelens.

Variety

  1. Since eyepieces are interchangeable, a telescope can be used at a variety of powers for different applications.
  2. Swarovski offers a variety of eyepieces to make sure you are perfectly equipped for any situation.
  3. Like all proper telescopes, the Astroscan can accept a variety of different eyepieces. (Web site)

Negative

  1. More highly corrected negative eyepieces have two or three lens elements cemented and combined together to make the eye lens. (Web site)
  2. In photomicrography special divergent (negative) lens systems are frequently used in place of the traditional eyepieces.

Performance

  1. Performance is fully consistent with the finest fixed focal length eyepieces.

Plane

  1. Some eyepieces have a movable "pointer" located within the eyepiece and positioned so that it appears as a silhouette in the image plane. (Web site)
