Compare the Tele Vue 8mm Delos and 8mm Plossl eyepieces for high-power planetary viewing. We break down the trade-offs in eye relief, field of view, and price to help you choose.
Quick answer
For comfortable, wide-field high-power viewing, choose the Tele Vue 8mm Delos; for budget-friendly sharpness on the Moon and planets, the Tele Vue 8mm Plossl delivers excellent on-axis performance.
Eye relief and viewing comfort
The Tele Vue 8mm Delos offers 20mm of eye relief, making it a strong choice for eyeglass wearers or anyone who values a relaxed viewing position. The 8mm Plossl has shorter eye relief, typical of Plossl designs at this focal length, which can feel cramped during long planetary sessions.
If you observe with glasses or prefer not to press your eye against the eyepiece, the Delos’s longer eye relief is a clear advantage. Without glasses, the Plossl’s shorter eye relief is manageable and many users find it perfectly acceptable.
Apparent field of view and immersion
The Delos delivers a 72° apparent field of view, giving a noticeably wider, more immersive window into the sky. The Plossl offers a narrower 50° field, which is more constricted but can help center the target and reduce sky glow in light-polluted areas.
For tracking planets at high power, the wider Delos field makes it easier to keep the target centered, especially on an undriven mount. The Plossl’s narrower field demands more frequent nudging.
Price and value
The Tele Vue 8mm Delos is priced at $255.42 (catalog comparison $387.00), while the 8mm Plossl is $68.68 (catalog comparison $101.00). The Plossl costs about a quarter of the Delos, making it an exceptional value for budget-conscious observers who prioritize sharp on-axis views.
The Delos’s higher price reflects its premium optical design, longer eye relief, and wider field. If your budget allows, the Delos offers a more comfortable and immersive experience without sacrificing image quality.
