TeleVue Plössl 25mm 50° 1.25″ Eyepiece
The TeleVue Plössl range covers focal lengths of 8, 11, 15, 20 and 25 mm - giving you a complete set for everything from planetary observing to wide deep-sky targets. The TeleVue Plössl 25mm eyepiece makes an excellent starting point for any eyepiece collection. Paired with a TeleVue Powermate, it effectively doubles the number of focal lengths available to you. Compared to the eyepieces supplied as standard with most telescopes, the difference in image quality and build quality is immediately clear.
Optics and image quality
The four-element design arranged in two groups delivers well-corrected images across the full field of view. Multi-coated lenses reduce reflections and preserve contrast - a real advantage when observing faint nebulae or fine planetary detail.
Comfortable viewing
The adjustable fold-down eyecup suits observers who wear glasses as well as those who do not. An eye relief of 17 mm keeps a comfortable distance between your eye and the eyepiece, reducing fatigue during longer sessions.
Parfocal and filter-ready
This eyepiece is parfocal with all other TeleVue Plössl models. When you switch between focal lengths, you need only minimal refocusing - a genuine advantage when working with a rotating eyepiece turret. The standard 1.25″ filter thread accepts any compatible filter without adapters.
Build quality
At 122 g, the eyepiece is solidly built without being unnecessarily heavy. It will not strain your focuser, even on lighter tripods.

Who is this eyepiece for?
The TeleVue Plössl 25mm suits beginners looking for their first quality eyepiece and experienced observers who want a reliable low-power option. It performs well on planets, star clusters, and extended deep-sky objects such as the Andromeda Galaxy or the Pleiades. If you already own other TeleVue Plössl eyepieces, the parfocal design means switching between them is quick and simple.
Why choose TeleVue?
TeleVue is one of the most respected names in telescope optics. Every TeleVue Plössl eyepiece is built to the same high standard, so you can expand your collection over time and always expect consistent performance. The 25mm focal length works well as a standalone purchase and pairs naturally with the rest of the Plössl range.
