Description Mid-range high power eyepieces like the 10mm 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; brightness and size of the object being observed are just a few aspects to consider. The observing challenges are high, but the rewards of observing at high power with razor sharp views are unforgettable. Comfort, Quality, Value.
