Tele Vue Plössl 11mm

A 11mm Tele Vue Plössl: the workhorse magnification where most galaxies, globulars and nebulae look their best, from the reference Plössl, the four-element design executed to the standard every other Plössl is judged against.

The spacewalk

You don’t look at a field.
You look into the sky.

Every number on the spec sheet matters less than one feeling: how much sky wraps around your eye. Widen the apparent field and watch the black edge of the eyepiece slip away.

50° apparent field

At 50°, you are aware of the field edge, like looking down a short, comfortable tube.

01What it's good at

What it's best at — and the trade-offs.

Immaculate build, coatings and QC that hold their value for decades.
Best at
✓Immaculate build, coatings and QC that hold their value for decades.
✓Reference-grade on-axis sharpness and contrast: the Plössl done exactly right.
✓At 11mm it lands squarely in medium power territory, exactly where most deep-sky objects look their best.
Trade-offs
!Short eye relief below about 12mm, the unavoidable Plössl compromise.
!A 50-degree field is narrow next to modern wide-fields.
!You pay a real premium over a budget Plössl for build and coatings, not extra field.
02In your telescope

One eyepiece. A different job in every scope.

44× in a small refractor, 185× in a long SCT

An eyepiece has no magnification of its own — the telescope decides. The same eyepiece becomes 44× and 1.1° of sky in a little refractor, or 185× and a tight frame in a long SCT. Here’s what it does across common scopes.

Exit pupil is how wide the beam of light leaving the eyepiece is. Around 5–6 mm is bright and immersive under dark skies; push much past 6 mm and you waste light, and under light pollution a smaller exit pupil shows more contrast.
03In plain English

The numbers, in plain English.

11mm FL · 50° AFOV · 1.25"
Focal lengthHigh power
11mm
About 109x in an 8 inch f/5.9 Dobsonian and 185x in an 8 inch SCT. A dependable high power for planetary detail and globular clusters that works on ordinary nights.
Apparent fieldClassic
50°
A narrow field by modern standards, and a deliberate trade: fewer air-to-glass surfaces mean less scatter and higher contrast than a wide-field eyepiece of the same power.
Eye reliefTight
8mm
Eight millimetres means viewing without glasses and keeping your eye close to the lens. This is the inherent limit of the Plössl design at short focal lengths rather than a shortcoming of this example.
BarrelStandard
1.25"
Fits any telescope's focuser or diagonal, and the light weight means no rebalancing when you swap it into a Dobsonian.
OpticsReference simple design
Fully multi-coated
A precisely made four-element design with full coatings. It is the benchmark other budget eyepieces are measured against, and it holds up because there is so little in the light path to go wrong.

05Role in a collection

Where it sits in your eyepiece case.

Where it sits across 3 focal lengths

A good eyepiece collection isn’t a pile of glass — it’s two or three focal lengths that hand off from wide to tight. This is the anchor at the bottom of the ladder: the one you find and frame with. You buy it once, and it stays your low-power eyepiece for life.

How it scores, and why.

72/100
72/ 100
Tele Vue Plössl 11mm

Judged as the workhorse magnification where most galaxies, globulars and nebulae look their best, it earns its score on reference-grade on-axis sharpness and contrast: the plössl done exactly right. Tighter eye relief at this focal length is the main thing holding it back. It is honest about being a specialist, not an all-rounder.

Buy it if you
✓Observers who want the workhorse magnification where most galaxies, globulars and nebulae look their best.
✓Observers happy to take their glasses off at the eyepiece.
✓Observers who value on-axis contrast over a sprawling field.
Look elsewhere if you
!Anyone who has looked through a wide-field eyepiece and cannot go back to a 52-degree tunnel.
!Eyeglass wearers, who will not comfortably reach the full field at this focal length.
!Planetary specialists who want the last ounce of high-power contrast from an orthoscopic.

Editor’s Take

Sweep it across a rich star field and the reason to own this focal length is obvious in a second. That is what the Plössl is for.
