The Meade Series 4000 8mm-24mm Zoom Eyepiece (1.25") # 07199-2 is an excellent addition to telescopes of all types, brands, and price levels from entry level to research grade. A terrific value, especially useful for terrestrial observation to zoon in on potentially moving wildlife.
Offers the ability to change magnifications "on the fly" yet demanding no compromise in performance. The eyepiece’s internal optics move on smooth, precisely machined surfaces which maintain optical collimation at all continuously variable zoom settings. The 6-element 4 group design has 15-18mm of eye relief, and provides an apparent field of view of 40° at 24mm, increasing to an apparent field of view of 60° at the highest power 8mm setting. All lenses are multi-coated for maximum light transmission and image contrast, while minimizing internal reflections.
Features a precision made 1.25" barrel, and fold down eyeguard for comfortable viewing and blocking stray light. The Series 4000 8mm-24mm Zoom Eyepiece (1.25") offers a complete focal length range from 8mm to 24mm (in a single eyepiece) without sacrificing resolution compared to fixed focal length oculars.
Product carries full one year Meade factory limited warranty (within US/Canada only).
Please Note: Zoom eyepieces will often produce a ratting sound when shaken. This is due to the clearances required for moving parts of the zoom mechanism, and does not indicate defects or lose lenses. This sound is especially prominent in Meade zoom eyepieces, but this is normal.
