Designed for high-power observing
The SVBONY 2.5mm SWA planetary eyepiece is intended for observers who want to push suitable telescopes to higher magnification when the atmosphere is unusually stable. Its 58° apparent field offers more viewing room than traditional narrow-field eyepieces.
- 2.5mm focal length: provides very high magnification in most telescopes.
- 58° apparent field of view: a comfortable viewing window for precision observations.
- 1.25-inch barrel: fits compatible 31.7mm telescope focusers and diagonals.
- Five-element optical design in three groups: a dedicated planetary eyepiece construction.
Is 2.5mm right for your telescope?
Divide your telescope's focal length by 2.5 to find magnification. A 500mm telescope gives 200×; a 750mm telescope gives 300×. These powers are demanding. Telescope aperture, optical quality, accurate focusing and atmospheric seeing determine whether the image will be sharp. A longer focal-length eyepiece will generally be more useful on average nights.

Frequently asked questions
Will this eyepiece work with any telescope?
It fits a standard 1.25-inch eyepiece holder, but the high magnification may be excessive for many telescopes and observing conditions. Check your telescope's focal length before choosing.
Is it suitable for planetary viewing?
Yes, especially for lunar and planetary detail when atmospheric seeing supports the magnification.
