The Series 5000 Ultra Wide Angle 5.5mm Eyepiece (1.25") from Meade is a great portal into space, featuring tack-sharp optical performance and a low amount of chromatic aberration. It features a wide 82° field of view, combined with comfortable eye relief, in a design that's a brilliant success both optically and mechanically. The Meade Series 5000 5.5mm Ultra Wide Angle Eyepiece is threaded to accept Meade's 1.25" astronomy filters. It's waterproof and parafocal with other Series 5000 eyepieces.
- Fully multicoated 7-element optics
- Blackened lens edges & internal metal surfaces increase contrast
- Adjustable twist-up eyecup for comfortable viewing with or without eyeglasses
- Parafocal eyepieces require very little focus adjustment, if any at all, when switching between other Series 5000 eyepieces
