Tele Vue Delos 24 mm Eyepiece
The Delos 24 mm is more than a window into the sky — it’s an invitation.
Born from Tele Vue’s legendary optical craft, this eyepiece transforms starlight into experience. Every element is tuned for contrast and comfort: a 72-degree apparent field, 22 millimeters of true eye relief, and glass polished to reveal the faintest edge of a nebula without strain or distortion.
Under dark skies, it does what Al Nagler loved most — it teaches through beauty. Each star field feels infinite yet intimate, wide but never wasted.
Optics
Tele Vue designed the Delos line to preserve the clarity and neutrality of its finest glass while expanding the field to an immersive 72 degrees. The 24 mm version captures the soul of that philosophy: pinpoint stars across the field, high transmission through fully multi-coated elements, and a balance between scale and serenity that suits both refractors and large-aperture reflectors.
Color is true, edge definition unwavering, and the background sky dissolves to black — not because of marketing claims, but because the optics earn it.
Mechanical Design
Machined from anodized aluminum and finished with an adjustable eyeguard, the Delos 24 mm feels deliberate in the hand. Its 2-inch barrel offers full illumination for deep-sky use, while the locking eyeguard sets an exact eye position that seals out stray light. Every click of the height adjuster feels like precision, built for observers who stay up long after the cold has settled.
Under the Night Sky
Aim it at the Pleiades, the Lagoon, or the lunar terminator — the Delos responds with crisp contrast and an ease that keeps you observing longer. The wide field feels natural, not exaggerated. You don’t scan; you drift. The stars simply exist, sharp to the edge, held in a quiet frame of optical discipline.
It’s an eyepiece that rewards patience: the longer you look, the more it shows.
Observer Impressions
Observers call the Delos line “effortless.” The comfort, the relief, the way the field seems to open without edge strain — these are not luxuries, but necessities for long sessions under the stars. The 24 mm sits at the heart of that series, bridging wide-field immersion and detailed clarity.
Observing Tip
Set the eyeguard to your natural eye height before focusing; once adjusted, the field holds steady and immersive. In moderate focal-length scopes, the 24 mm provides the ideal bridge between finder and detail eyepieces — wide enough to navigate, precise enough to study.
Final Thoughts
The Delos 24 mm is not an accessory — it’s a teacher in glass and metal.
Every time you lift it to the night, it reminds you why you started looking up.
For those who see astronomy not as a hobby but as a dialogue with the universe, this eyepiece answers fluently.
