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 […]

Description The 11mm 82° Series Waterproof Argon-Purged Eyepiece is a popular focal length in the upper-medium power magnification class providing both super-wide apparent field and generous eye relief. It is perfect for any application where more power is desired including observing globular star clusters, planetary nebulae, the bright cloud structure near the nucleus of comets, […]
