Best eyepiece for the Sky-Watcher Skymax 127
Which eyepiece gets the most out of the Sky-Watcher Skymax 127, chosen by exit pupil rather than by guesswork.
- Aperture / focal length
- 127 mm / 1540 mm (f/12.1)
- Deep-sky pick
- Celestron X-Cel LX 25mm: 62x, 2.06 mm exit pupil
- Low-power pick
- Celestron Omni 56mm Plossl: 28x, 4.62 mm exit pupil
- Focuser barrel
- 2 in (both eyepieces fit)
For deep-sky detail, the Celestron X-Cel LX 25mm is the pick of the eyepieces here: at 62x it lands near the 2 mm exit pupil where faint-object contrast peaks in the Sky-Watcher Skymax 127. For wide low-power sweeping, drop to the Celestron Omni 56mm Plossl at 28x.
An exit pupil near 2 mm is the classic sweet spot for teasing detail out of faint deep-sky objects, because it concentrates the light while keeping the image bright enough. In the Sky-Watcher Skymax 127 the Celestron X-Cel LX 25mm lands there, at 62x with a 2.06 mm exit pupil and a 0.97 degree field.
For a low-power finder-and-framing view you want a wider exit pupil, around 5 mm. Here the Celestron Omni 56mm Plossl gives 28x, a 4.62 mm exit pupil and a 1.71 degree field, the widest true field of the eyepieces that fit this focuser.
