Alpine Astronomical Baader 32mm Classic Plossl Eyepiece with Extender Tube (1.25")

Employing a classic Plossl design and engineered primarily for planetary viewing, the Alpine Astronomical Baader 32mm Classic Plossl Eyepiece makes an ideal addition to your observational kit. It produces a relatively low magnification on most optical tube assemblies (OTAs), with a generous 50° apparent angle of view. This model is parfocal with Baader ortho eyepieces, which means there is little to no need to refocus when changing eyepieces within the ortho line.

The eyepiece features a 4-element/2-group lens design with a triplet-element and one plano-convex eye lens, so there are only four glass-air surfaces to limit internal diffraction and light loss. True high-transmission (HT) multi-coatings on all glass-air surfaces yield brilliant images while virtually eliminating internal reflections. When paired with the lens design, this delivers a pure-white image with improved sharpness and contrast. The interior of the anodized housing is blackened to suppress stray light and has machined threads to accept most standard 1.25" filters. The eyepiece is made with a standard 1.25" barrel so it is compatible with the most popular-sized holders and accessories. Alpine outfitted it with a winged eyecup to block stray terrestrial light to improve brightness and contrast, and a slip-on eyeguard extension tube that permits the eyeguard to be positioned further back for use with a Barlow lens or if the user prefers a shorter eye relief.
