What it's for

Low power · wide fieldHigh power · narrow field

A medium-power eyepiece for the heart of deep-sky observing, galaxies, globulars and planetary nebulae at a comfortable scale. Immersive and razor-sharp, sitting between the wide-field sweeper and the high-power planetary eyepiece.

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.

72° apparent field

At 72°, the black rim sits out at the corner of your attention rather than in front of you.

01What it's good at

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

Best at

✓A full 20 mm of eye relief at a medium focal length, making the most-used power in the case effortless.

✓Pinpoint stars and high contrast to the edge of the 72-degree field, even in fast scopes.

✓The magnification where galaxies and globulars are at their best, delivered with reference sharpness.

Trade-offs

!Expensive for a single focal length, and you'll want a wide and a high-power partner too.

!Heavy; a full case of Delos eyepieces will rebalance a light Dob or refractor.

!The 72-degree field is generous but not the ultra-wide immersion of an 82 or 100-degree design.

02In your telescope

One eyepiece. A different job in every scope.

An eyepiece has no magnification of its own — the telescope decides. The same eyepiece becomes 34× and 2.1° of sky in a little refractor, or 145× and a tight frame in a long SCT. Here’s what it does across common scopes.

Small apo refractor

480 mm · f/5.5

Magnification

34×

True field

2.1°

Exit pupil

2.5 mm

A wide, comfortable 34x and 2.1 degrees in the little refractor, sharp across the whole field.

86x and a 50-arcminute field in the 8-inch Dob, the deep-sky sweet spot for galaxies and globulars.

12-inch Dobsonian

1500 mm · f/5

Magnification

107×

True field

40′

Exit pupil

2.8 mm

107x in the big Dob with pinpoint stars to the edge, ideal for planetary nebulae and brighter galaxies.

8-inch SCT

Magnification

145×

True field

30′

Exit pupil

1.4 mm

145x out of the long SCT, medium-high power detail with easy, relaxed viewing.

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.

02In plain English

The numbers, in plain English.

20 mm eye reliefThe signature spec

Effortless

You sit back and observe with glasses on, comfortable for the long stretches medium-power deep sky invites.

72° apparent fieldWide, not ultra-wide

Immersive

Enough field to let deep-sky objects sit in space without the size and cost of a 100-degree eyepiece.

Edge sharpnessHolds at f/5

Pinpoint

Stars stay tight and neutral to the field stop even in fast scopes, so the whole field is usable.

~350 gRebalances light scopes

Substantial

You'll feel it in a small refractor or grab-and-go Dob; a fair trade for the view and comfort.

03What comes alive

The targets this eyepiece was born for.

Comes alive

M13 Hercules Cluster

Resolves into thousands of stars in an 8-inch and up, set in a sharp, dark field.

Comes alive

Ring Nebula

Lifts from a smoke ring to a structured, three-dimensional shell at this scale.

Comes alive

Bright galaxies

M81, M82 and the brighter Messier galaxies show shape and dust lanes at a comfortable power.

Excellent

Saturn

The rings and Cassini Division sit sharp and steady, with room to watch the planet drift.

Excellent

Double stars

Tight pairs split cleanly on the high-contrast, edge-sharp field.

Excellent

Planetary nebulae

The Blinking Planetary and similar targets reward the medium power and sharp field.

04Role in a collection

Where it sits in your eyepiece case.

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.

The telescope

What it goes into

Any scope, fast or slow

Its edge correction flatters Newtonians and refractors alike at medium power

8-inch and up for deep sky

Aperture turns the medium power into resolved globulars and structured nebulae

$Apo refractor$

Apo refractor

A clean apo and the Delos is a superb galaxy and planetary-nebula pairing

What transforms the view

1.25" OIII filter

Planetary nebulae like the Ring take a filter well at this power

Lifts fainter nebulae without washing out the stars

02The Polaris Score

How it scores, and why.

91/ 100

Tele Vue Delos 14mm

As a medium-power all-rounder it is close to flawless: sharp, high-contrast, and uniquely comfortable across the most-used magnification in the case. Its only real marks are price and weight, never the view.

Value

Polaris weighs how well the eyepiece does the job it was designed for — optics, immersion, comfort and value — never list price or brand.

03Who it's for

An honest fit check.

Buy it if you

✓You want the single most-used magnification in the case rendered as sharply as your scope allows, with zero eye strain.

✓You wear glasses or simply value the relaxed 20 mm of eye relief for long sessions.

✓You own a fast scope and want pinpoint stars to the edge without a corrector.

✓You are filling the medium-power slot of a buy-once eyepiece case.

Look elsewhere if you

!You want the widest true field for sweeping; a long-focal-length wide-angle does that job.

!You mainly chase planets and want maximum power, where a 6 to 8 mm eyepiece serves you better.

!You are budget-conscious, where a Celestron X-Cel or Explore Scientific gives much of the view for far less.

!You need it to stay light; at over 350 grams it can rebalance a small scope.

Editor’s Take

If a case could hold only one high-quality eyepiece, the 14 mm Delos would be a serious candidate: the magnification where galaxies, globulars and planetary nebulae are all at their best, delivered without a hint of eye strain.

A step up in power

Tele Vue Delos 10mm

The same comfortable design at higher magnification, for planets and smaller deep-sky objects.

The rival

Pentax XW 14mm

The other 20mm-eye-relief medium-power reference, weather-sealed, the classic head-to-head.

Budget alternative

Celestron X-Cel LX 12mm

Much of the comfort and a good sharp view for a quarter of the price, if the Delos is a stretch.
