Why this eyepiece?
- ✓Frames all of Moon in a single view
- ✓Sweeping, immersive low-power view
- ✓Wide, bright exit pupil — best under dark skies
Tradeoffs
- –Less reach to push fine detail in the subject
Large exit pupil may waste light
Half a degree of crater fields, and the first thing almost everyone points a telescope at. Bright enough for any aperture — the limit is seeing, not light.
