Select eyepieces, focal extenders up to 20% off for only 6 more days!

Transform your
observing experience!

Only six days left to save up to 20%
on select waterproof eyepieces

An eyepiece is more than a simple accessory. It is a critical component in determining how profoundly you connect with the cosmos.
Explore Scientific's premium waterproof eyepieces are designed to maximize your telescope's potential and take your observing experience to the next level. The line offers seven distinct series with apparent fields of view of 52°, 62°, 68°, 82°, 92°, 100° and a hyper-wide 120°.
Throughout April, select eyepieces in all seven of these series are on sale for up to 20% off.
The lenses in these precision eyepieces are made of low-dispersion glass with a high refractive index and are fully multi-coated with durable enhanced multi-layer deposition (EMD) coatings. The combination of these factors brilliantly captures the celestial wonders you seek with sharp contrast, high resolution and crisp definition.
To protect the precision optics, the body of each eyepiece is O-ring sealed and purged with an inert gas for a waterproof environment that is impervious to internal fogging and prevents contaminants like fungus and dust from entering. Each also offers foldable soft silicone rubber eyecups to provide the most comfortable viewing experience and a filter thread on the backside that will allow for use of moon or light filters.

Focal extenders are 20% off
for a limited time

Available in 2x, 3x and 5x in a 1.25" barrel and a 2x and 3x in a 2" barrel, our focal extenders add versatility to your eyepiece line-up by allowing each eyepiece to perform at two powers.
For example, if your particular eyepiece/telescope combination results in a 50x power, adding a 2x focal extender will change that to a 100x power.
To guarantee superior image quality, our focal extenders use multiple lens elements that are made of high-quality glass and fully multi-coated with EMD coatings to reduce chromatic and spherical aberrations.

Bresser 70° eyepieces also 20% off

These non-waterproof oculars are a significant step up from a classic Plössl design. Available in six focal lengths, these eyepieces use premium multi-coated glass and a five-element design to outperform traditional Plössl eyepieces in key functions like correcting chromatic abberations and maximizing edge sharpness.
