Best eyepiece for the Celestron NexStar 6SE
Which eyepiece gets the most out of the Celestron NexStar 6SE, chosen by exit pupil rather than by guesswork.
- Aperture / focal length
- 150 mm / 1500 mm (f/10)
- Deep-sky pick
- Celestron Omni 15mm Plossl: 100x, 1.5 mm exit pupil
- Low-power pick
- Celestron Omni 56mm Plossl: 27x, 5.6 mm exit pupil
- Focuser barrel
- 2 in (both eyepieces fit)
For deep-sky detail, the Celestron Omni 15mm Plossl is the pick of the eyepieces here: at 100x it lands near the 2 mm exit pupil where faint-object contrast peaks in the Celestron NexStar 6SE. For wide low-power sweeping, drop to the Celestron Omni 56mm Plossl at 27x.
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 Celestron NexStar 6SE the Celestron Omni 15mm Plossl lands there, at 100x with a 1.5 mm exit pupil and a 0.5 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 27x, a 5.6 mm exit pupil and a 1.75 degree field, the widest true field of the eyepieces that fit this focuser.
