Description Explore Scientific cradle assemblies fit their appointed telescope OTA snuggly, yet protect the delicate surface of the tube. The hinged ring system separates easily by loosening the over-sized metal thumbscrews, and locks securely back into place once the OTA has been nestled inside the rings. Each extruded aluminum ring set is topped with a […]

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 […]

Description Mid-range high power eyepieces like the 6.5mm are instrumental when transitioning through magnifications to observe an object until it is best seen. There are several aspects that have to come together when observing at high powers: good-to-perfect atmospheric seeing conditions; telescope optics that are collimated; a telescope that is acclimated to the ambient temperature; […]

Description Eyepieces at or near the 10mm range are often considered a mandatory focal length in your collection, as this focal length range is departure point from medium power eyepieces for most telescopes for amateur astronomers. Fainter deep sky objects that do not have the inherent brightness to be observed at higher powers are often […]

Description Solidly in the mid-magnification range for most amateur telescopes, the 15mm is a true workhorse for visual observers. If you love deep sky observing, eyepieces in this focal length range not only give healthy increases in magnification, but the contrast enhancement of giving a darker background sky can make all the difference of how […]

Description Often considered the perfect mid-range focal length for most amateur telescopes, the 20mm on the ED127 at f7.5 produces a 1 degree true field of view. Perfect for the Messier Marathon, or running down the Herschel Catalog. The 20mm 52° Series is also a good selection for most binoviewers with its relatively small size […]

Description Long considered the “standard” eyepiece that is often supplied with telescopes that are sold by various suppliers, the 25mm focal length category is perhaps the most used eyepiece in the world. Like the 20mm, these eyepieces are great for binoviewer devices, and the 25mm is probably the longest focal length of the mid-power range […]
