For years zoom eyepieces were regarded as "convenient," but without the optical resolution required in demanding astronomical applications. Meade Series 4000 8mm-24mm Zoom Eyepiece (1.25") 07199-2has changed that impression - completely and forever. Because, finally, this is a Zoom 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 eyepieces.
Meade 8mm-24mm Zoom Eyepiece Series 4000 #07199-2 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 designersof photo-optical instruments, this 7-element system provides an apparent field of 40° at the 24mm setting, increasing continuously to a 55° field at 8mm. The internal zoom 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 filters.
With its high-eyepoint optics and foldable rubber eyecup the Meade Series 4000 Zoom 1.25" Eyepiece is comfortably usable by eyeglass wearers; even with eyeglasses the entire field of view is easily observable.
