Tele Vue 25mm Plossl Eyepiece
This Tele Vue 25mm Plossl eyepiece fits a standard 1.25 inch focuser and provides a 50 degree apparent field of view. It is designed for visual observers who want a reliable wide-field option. The 17mm eye relief suits users who wear glasses during sessions. High-index glasses improve edge-field performance across the view.
Practical Limits of 1.25 Inch Barrel
The 1.25 inch barrel diameter restricts the maximum field stop size, which caps the true field of view at longer focal lengths. A 25mm focal length in this format delivers a wide apparent field but cannot match the true field possible with larger two inch barrels. Observers seeking maximum true field for large deep-sky objects will hit this physical constraint.
25mm Focal Length Determines Power
The 25mm focal length sets the magnification when divided into the telescope focal length. It produces low to medium power views suited for large nebulae, star clusters and lunar panoramas. Buyers who need higher planetary magnification or a shorter focal length for specific framing should choose a different model.

Questions about this item
Which focal length should I choose between the 25mm Plossl and other available eyepieces?
The 25mm focal length provides lower magnification and a wider true field of view compared to shorter focal lengths, making it suitable for deep-sky objects and large star fields.
What does the 50 degree apparent field of view mean when I look through the eyepiece?
A 50 degree apparent field gives a moderately wide viewing window, showing a generous patch of sky without the tunnel vision of narrower designs.
Will the 1.25 inch barrel fit my telescope's focuser or diagonal?
The 1.25 inch barrel is the standard size for most amateur telescopes and diagonals, so it will fit directly without an adapter.
