Tele Vue Panoptic 24mm

The widest true field a 1.25-inch barrel can physically give, rendered flawlessly. If you own one premium eyepiece, most observers make it this one.

What it's for
Low power · wide fieldHigh power · narrow field

A low-to-medium-power eyepiece for finding and framing, and the widest true field possible in a 1.25-inch focuser. Immersive and razor-sharp, but not a high-magnification planetary tool.

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.

68° apparent field

At 68°, 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.

The 27 mm field stop is the physical maximum for a 1.25-inch barrel, so nothing in the format shows more true sky.
Best at
✓The 27 mm field stop is the physical maximum for a 1.25-inch barrel, so nothing in the format shows more true sky.
✓Pinpoint stars and high contrast to the edge even in fast Newtonians, the reference for correction in this class.
✓The single most-recommended premium eyepiece for a reason: it does the most-used job in the case flawlessly.
Trade-offs
!Only 15 mm of eye relief, tighter than the Delos or Pentax lines for glasses wearers.
!Premium price for a 68-degree field when budget rivals get close on paper.
!A 2-inch wide-field will frame more true sky if your focuser allows it.
02In your telescope

One eyepiece. A different job in every scope.

20× in a small refractor, 85× in a long SCT

An eyepiece has no magnification of its own — the telescope decides. The same eyepiece becomes 20× and 3.4° of sky in a little refractor, or 85× 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
20×

A gorgeous 20x and 3.4 degrees in the little refractor, sharp corner to corner, framing the largest nebulae whole.

True field

62x in the big Dob with a 4.8 mm exit pupil, rich low-power deep sky in a dark surround.

Magnification
85×
True field
48′
Exit pupil
2.4 mm
Tames the long SCT to 85x and 0.8 degrees, one of the widest true fields you can wring from an f/10.
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.

24mm FL · 68° AFOV · 1.25"
27 mm field stopAs wide as 1.25" gets
The maximum
This is the widest true field any 1.25-inch eyepiece can physically show; nothing in the format frames more sky.
68° apparent fieldSharp to the edge
Immersive
Wide and, crucially, corrected: the whole field is usable, not just the middle, even at fast focal ratios.
Edge correctionHolds at f/4
Reference
Stars stay tight and neutral to the field stop in fast scopes, the benchmark the whole class is measured against.
15 mm eye reliefTight for glasses
Adequate
Comfortable bare-eyed, but glasses wearers may not see the whole field; the Delos trades a little field for far more relief.

The PleiadesComes alive
The Pleiades
The whole cluster framed with room to spare, sharp blue stars against a dark field.
Andromeda GalaxyComes alive
Andromeda Galaxy
Bright at low power with both companions in the same field, and no soft edges to spoil it.
Orion NebulaComes alive
Orion Nebula
The Sword region framed whole, with the nebula's wings crisp against the surrounding stars.
The Double ClusterExcellent
The Double Cluster
Two open clusters side by side in one sharp, contrasty low-power view.
M31 star fieldsExcellent
M31 star fields
Sweeping the Milky Way, pinpoint stars right to the field stop make the richest fields sing.
Large globularsExcellent
Large globulars
M13 and M22 sit in a wide, dark surround, ready for you to zoom in with a shorter eyepiece.
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.

Tele Vue Panoptic 24mm

As the reference low-to-medium-power 1.25-inch eyepiece it is essentially without fault: the maximum true field the barrel allows, held sharp and contrasty to the edge. It is not cheap, but nothing does this job better.

Buy it if you
✓You want the widest, sharpest low-power view a 1.25-inch focuser can produce, with no compromise on correction.
✓You own a fast scope and want stars to stay pinpoint to the very edge without a coma corrector doing all the work.
✓You are building a buy-once case and want the find-and-frame slot filled for life.
✓You value flawless contrast on faint deep-sky objects over an ultra-wide apparent field.
Look elsewhere if you
!You have a 2-inch focuser and want the absolute widest field, where a 2-inch eyepiece frames more sky.
!You mainly chase planets and the Moon, which want a short focal length, not this.
!You are on a tight budget, where an Explore Scientific 24mm gives most of the view for a third of the price.
!You want the enveloping feel of an 82 or 100-degree field; 68 degrees is generous but not ultra-wide.

Editor’s Take

The Panoptic 24 sits at a hard physical limit, the largest field stop a 1.25-inch barrel allows, and Tele Vue simply made that limit perfect. It is the eyepiece people quietly keep for thirty years and hand to their kids.

For a different goal, start here.

3 alternatives, each mapped to the goal it wins at
Slightly wider

Tele Vue Panoptic 27mm

A hair more true field in a 2-inch barrel, for a larger, pricier body and the same flawless correction.

Budget alternative

Explore Scientific 68deg 24mm

The same 24mm and 68 degrees for a third of the price, giving up some edge polish and contrast.

More reach, more relief

Tele Vue Delos 14mm

Steps up in power with a full 20 mm of eye relief, if comfort at higher magnification matters more than field.

Portable Travel Rig

Featured

Grab-and-go refractor for casual observing and travel. The Evostar 72ED and the Twilight Nano together weigh less than a folding chair, and the mount is a simple alt-azimuth — up and down, left and right, no alignment. Set it on the ground, drop the tube on, and you are looking at something inside a minute. The Panoptic 24mm gives just under 4° of true field; add the 35mm when you want the widest view the little scope can produce.
