Tele Vue Plossl Overview

Engineered to Al Nagler's uncompromising standards but at an entry-level price, the medium-focal length Tele Vue Plossl 15mm Eyepiece produces a moderate magnification on most OTAs for both near and deep-sky observations.

It is made using diffraction-limiting high-index glass lenses in a 4-element/2-group configuration to keep light on-axis and reduce astigmatism and edge-aberrations across its generous 50° apparent field of view. Fully multi-coated optics, blackened lens elements, and anti-reflection threads complement the optical components to improve contrast and light transmission, while limiting its loss. Its 10mm eye relief allows users the room to back off slightly from the eyecup for a more comfortable viewing experience with a reduced risk of accidental contact with the eyepiece lens which can cause vibrations and interfere with views. Ideal for fast-focal ratio OTAs, the eyepiece features a standard 1.25" barrel to be compatible with the most popular size of focuser and accessories, with a convenient fold-down rubber eyecup. This model of the Plossl series is parfocal with all Tele Vue Group 'B' eyepieces, allowing you to change compatible eyepieces without having to refocus — saving time and limiting vibrations.

... the short eye relief bothers me.

a gem in the Tele Vue plossl line

Even with a short tune achromat scope and the powermate 2.5, the views are tack sharp and as good as could be. The 15mm shines in the plossl series. I'm not saying the other pieces are not good; they are all superb eye pieces, but there is something about this one that stands above the rest.

Beautiful clear bright images of the moon last night. Perfect balance between a 25 mm and an 8 mm eyepiece.

I use this with a 90mm Coronado H Alpha solar telescope and the viewing is crisp, prominences show great detail. I also tried it with a 25 Obsession telescope and the views were very good for a Plossl eyepiece.

A simple plossl design. I use it on an f/5 newtonian 5 so it gives me a comfortable 3 mm exit pupil and has a 10 mm eye relief. With my scope, it is just right to observe the full disk of the sun or the moon, but still bring in a fairly wide field of starts too.

Good eyepiece

This is slightly better than my other plossls but it should be considering it is about 6x the price!

Excellent eyepiece

Hey, it's a Tele Vue. Well made, Great quality. Leaps and bounds better than the pieces that come with most scopes. Important to remember that your eyepiece is just as important as your primary optics.

What I feel that needs to be better explained about eyepieces and focal lengths as in 6mm or 25mm is that the opening is tiny for 6 mm as compared with 25mm that is wider . The lower the focal length the difficult it gets to train your eye throughthe opening due to its tiny opening. My child experience with my first kid telescope that came with 6mm and 25mm eyepieces told me that 25mm is more enjoyable to use despite lower magnification than the higher magnifying 6mm which is so restrictive in the opening for my eye to keep peeking through as steadiily as I can. I think that a minimum of 10mm is acceptable to me or maybe 12mm. . Am I correct?

yes, you are correct. if you get a plossil eyepiece (4 element) the higher magnification eyepieces will have a smaller opening. If you go to a 6, 8 element eyepiece you will be able to go to a higher magnification with a larger opening.
