Eyepieces & Telescopes

Explore Scientific is known for both premium telescopes and highly regarded telescope eyepieces, and this collection brings the two together. Browse apochromatic ED refractors, AR achromatic refractors, Newtonian reflectors and Dobsonian telescopes alongside our waterproof eyepiece lines, so you can plan a complete, well-matched observing setup in one place.

Choosing the right eyepieces for your telescope determines magnification and field of view: shorter focal lengths for high-power planetary detail, longer focal lengths for wide views of clusters and nebulae. Our eyepiece series range from value-focused 52° and 62° designs to wide-field 68° and ultra-wide 82°, 92° and 100° options. Pairing quality optics in both your telescope and eyepieces is the best way to enjoy sharp, high-contrast views of the Moon, planets and deep-sky objects for years to come.

A simple rule of thumb: divide your telescope's focal length by the eyepiece focal length to find magnification, and remember that a telescope's useful maximum magnification is roughly 50 times its aperture in inches. Most observers spend the majority of their time at low and medium power, so a quality wide-field eyepiece is often the best first upgrade. Whether you are buying your first telescope or expanding an advanced setup, choosing your telescope and eyepieces together ensures every part of your optical system works in harmony for the best possible views.
