Are Plossl eyepieces good?

Are Plossl eyepieces good?

Plössl eyepieces are good all-around performers, producing sharp images at the center of the field, but they have only four lens elements. Better edge correction with a short-focus telescope is one of the things you pay extra money for, and sophisticated eyepiece designs have as many as eight elements.

Are TeleVue eyepieces good?

The DeLite eyepiece series from Tele Vue delivers an optically excellent view together with the option to physically adjust the distance of your eye from the eye lens, whether you wear glasses or not. This makes it really easy to place your eye at the correct ‘eye relief’ to get the best view possible.

Are TeleVue Plossls worth it?

The Televue Plossl consistently gave outstandingly better edge of eyepiece performance, far more contrast and sharper images. When Jupiter would near the edge of the eyepiece field, it didn’t distort! Telescope after telescope… Focal length after focal length… Same results.

Where are TeleVue Plossl eyepieces made?

All TeleVue eyepieces are made in either Japan or Taiwan. The Plossls are one of their lines that to the best of my knowledge have always been manufactured in Japan, to TeleVue’s specs.

What is the difference between Kellner and Plossl?

Kellner eyepieces have decent eye relief, a fair field of view (45 degrees) and little curvature of field. The Plossl eyepiece is composed of two doublets, which are identical to each other. For this reason, you will also hear it called a symmetrical eyepiece.

Which eyepiece is best for viewing planets?

The focal length of the telescope is 900mm, so to achieve the maximum useful magnification, then a 4.5mm eyepiece would be ideal. One of the best parts about planetary viewing or imaging is that since the objects are so bright, you can do it just about anywhere regardless of light pollution.

Where are TeleVue telescopes made?

Chester, New York
Every TeleVue refractor is assembled, collimated and tested at their facility in Chester, New York.

Where are Explore Scientific eyepieces made?

Springdale, Arkansas
Roberts in 2008. Headquartered in Springdale, Arkansas, the company designs and manufactures telescopes, spotting scopes, binoculars, microscopes and other scientific devices. Products are manufactured in China by JOC and imported.

What does a Plossl eyepiece do?

These eyepieces produce a ‘standard apparent feld of view’ of between 50° and 56° with most set at around 52°. This general purpose design gives good colour correction and an adequate feld of view at reasonable cost and they are often bundled with new telescopes.

Where are Nagler eyepieces made?

Please don’t consider this a definitive answer, it is more a snapshot, but looking along our shelves I can see most of the Plossls, all the DeLites and half the Naglers are made in Japan.

Are Kellner eyepieces any good?

Kellner eyepieces have decent eye relief, a fair field of view (45 degrees) and little curvature of field. It is an excellent eyepiece and many observers look no farther than a good set of Plossls. They have a wide field of view (55 degrees), very good eye relief and are well corrected for aberrations.

Which telescope lens is stronger 10mm or 20mm?

The most important eyepiece characteristic is focal length. This means that a smaller number on an eyepiece gives a higher magnification. A 10mm eyepiece would provide twice as much magnification as a 20mm eyepiece. It also means that the same eyepiece gives different magnifications on different scopes.
