A comfortable view of the Moon and planets.
The Orion Edge-On Planetary 14.5mm eyepiece pairs a flat-field optical design with generous eye relief. Magnification depends on your telescope: divide its focal length in millimetres by 14.5.
20 mm eye relief
A generous viewing distance lets you observe without pressing your eye close to the lens.
Fully multi-coated optics
The seven-element optical design uses multiple anti-reflection coatings to help light pass through the lenses.
Fits a 1.25-inch eyepiece holder.
A folding rubber eyeguard lets you adjust how you position your eye. The barrel also accepts screw-in 1.25-inch eyepiece filters.
