Chromatic aberration is the main enemy of a good telescope image. You can't do much about atmospheric aberration, but a good lanthanum eyepiece is always a step in the best direction. Orion 8-24 mm Pro Lanthanum is:
• eyepiece with smoothly variable focal length in the range of 8-24 mm, which of course also means smoothly variable magnifications
• parfocal eyepiece in the whole focal range - once sharpened the image does not require changing the focus when changing the magnification
• great optics - 8 elements in 6 groups, of which 5 elements are made of lanthanum glass (!)
• retractable eyecup ("twist-up") allows you to adjust the optimal distance from the eye, and the eye relief is large and constant throughout the entire focusing range, equal to 20 mm
• waterproof eyepiece - it won't hurt the rain if we observe nature in worse weather • focal length: 8-24 mm (zoom)
• AFOV (own field of view): 40-60 °
• construction: 8 elements
• parfocality across the entire focal range: yes
• layers: FMC (optics fully covered)
• exit pupil offset: 20 mm in the whole focal range (!)
• filter thread: yes, 1.25 "(M28.5 x 0.6)
• eyecup: screwed, rubberised
• body: aluminum + rubber for a better grip
• casting standard: 1.25 "
