Vixen manufactures their fine-quality LanthanumEyepiece series in two variations - the 'standard' and the Lanthanum Wide variants. Both lineups have multicoatings upon every air-to-glass surface within the eyepiece, and do so at a comparative value versus other premium units in the marketplace.
This big 2" Lantanum Wide NLVW 30mm optic is meant to deliver you broad, lower-magnification viewing of galaxies and other large-sky-angle objects. With its 65° apparent field and nearly-identical resolution across its entire viewing, you'll enjoy feeling surrounded by a field that has Plossl-level sharpness uniformity. As an "NLVW" unit, it has a newer turning-style eyecup.
Helicoid-type, soft rubber eyecup
Fantastic eye relief for both eyeglass observing & eyepiece projection photography
