عدسة عينية Baader Planetarium Classic Ortho 18mm بقطر 1.25 بوصة - BCO-18

The 18mm focal length gives me crisp lunar details I couldn't catch with my older eyepieces, and the 1.25" barrel fit snugly into my focuser. Eye relief is comfortable even for my glasses.

Compared to my plossl eyepieces, the image sharpness across the entire field is noticeably better, especially on the moon. The eye relief is tight, but the contrast this ortho delivers on Jupiter more than makes up for it.

The 18mm focal length on this one gives a wonderfully relaxed viewing experience—no eye strain even after a half-hour on the Moon. The orthoscopic design keeps stars as tight pinpoints right to the edge, which is something I rarely see in this price range.
