Description The Explore Scientific 4.7mm 82 ° Series Argon-Purged Waterproof Eyepiece is used when very high magnifications are desired. Watch the video on this page below starting at 5:28 where we describe the benefits and conditions that are required to use your telescope at high magnifying power for planetary and double star observations, and for […]

Description The 6.7mm 82 degree eyepiece is great for planetary detail, and does not require the perfect seeing conditions needed for higher magnifications. When using this eyepiece with big refractors, it will often be the ultimate eyepiece under normal viewing conditions. Messier 1, the Crab Nebula with our 152mm telescope will astound you. If this […]

*Note that this is a discontinued product. This legacy information is for reference only. See our 8.5mm 82° Series LER Waterproof Eyepiece. Description The 8.8 mm focal length is perfect for observing objects that would benefit from higher magnifications, but that also require a bigger field of view. With our bigger refractor telescopes (127mm and […]

Features Huge apparent field of view not only gave the observer a panoramic visual experience, but they relax the eye so the observer could pay attention to subtle details for extended periods. Each 100° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas. This also maximizes the life of the […]

Description The Explore Scientific 9mm 120° Series eyepiece really is in a class by itself. The 120° apparent field of view is unlike anything you have experienced before. Normally, when we look through hyper wide field eyepieces, we see a huge swath of the night sky at low magnification. With the 9mm 120°, however, you […]

Description A new focal length joins the Explore Scientific line of inert gas-purged Waterproof Eyepieces with the 3mm 52° Series Eyepiece. A logical companion for the “grab-and-go” ED80mm f/6 Air-Spaced Triplet, this eyepiece produces 160X which will perform very well with good seeing conditions. On the ED152 at f/8, 405X is achieved without the use […]

Description High power eyepieces (e.g. 3mm to 10mm) are used not only for obvious observations of planets and double stars, but can be employed for bright, compact deep sky objects. Not only will the scale of an object like a planetary nebula or globular cluster be impressive as it fills the eyepiece FOV, but the […]
