About the Meade Series 4000 8mm-24mm Zoom Eyepiece - 1.25"...
For years zoom telescope eyepieces were regarded as "convenient," but without the optical resolution required in demanding astronomical applications. Now, the Meade Series 4000 8mm-24mm Zoom Eyepiece has changed that impression - completely and forever. Because, finally, this is a Zoom Meade Telescope Eyepiece designed for the advanced amateur astronomer who is uncompromising in his or her optical performance specifications. Performance is fully consistent with the finest fixed focal length telescope eyepieces.
The Meade 8mm-24mm Zoom Eyepiece is an excellent addition to telescopes of all types, brands, and price levels, whether 60mm refractor, 8" Dobsonian, 90mm ETX, or 12" LX200 Schmidt-Cassegrain.
Conceived by one of the world''s leading designers of photo-optical instruments, the Meade 8mm-24mm Zoom Eyepiece 7-element system provides an apparent field of 40 degrees at the 24mm setting, increasing continuously to a 55 degree field at 8mm. The internal zoom Meade Telescope Eyepiece optics move on smooth, precisely machined surfaces which maintain optical collimation at all zoom settings. A scale graduated in 1mm units indicates the zoom focal length in operation. All lenses are multi-coated for maximum light transmission and image contrast, while minimizing internal reflections. The chromed brass barrel is threaded for Meade Eyepiece Filters.
With its high-eyepoint optics and foldable rubber eyecup the Meade 8mm-24mm Zoom Eyepiece is comfortably usable by eyeglass wearers; even with eyeglasses the entire field of view is easily observable.
