TeleVue DeLite 3mm : 62\u00b0 1,25″ Oculair: DeLite-oculair met 62 graden beeldveld<\/strong><\/h2>\n\n\n\n

The DeLite 3mm is the highest magnification in the series and is intended for planetary detail in calm conditions. With a 20mm eye relief, you can comfortably observe even at this focal length.<\/p>\n\n\n\n

The DeLite series is designed as a compact version of the Delos: the same principle of a long eye relief, but with a 62-degree field of view and a smaller housing. This makes the series suitable for mounts and binoviewers where weight is a factor.<\/p>\n\n\n\n

62 degrees with a long eye relief<\/h4>\n\n\n\n

The DeLite series is designed as a narrower Ethos field of view with more eye relief. By keeping the apparent field of view at 62 degrees, TeleVue was able to bring the eye relief to 20mm without making the eyepiece unmanageably large.<\/p>\n\n\n\n

For eyeglass wearers, that's the difference between seeing the full field of vision and missing a part of it. Even without glasses, you're looking more relaxed because your eye doesn't have to push against the lens.<\/p>\n\n\n\n

When 3 mm makes sense<\/h4>\n\n\n\n

On a telescope with a 1200 mm focal length, this eyepiece provides 400x magnification. That requires an aperture of over 200 mm and a night with stable air.<\/p>\n\n\n\n

If the seeing isn't cooperating, a longer focal length will reveal more detail on the same night. Judge the magnification on a per-night basis, not per telescope.<\/p>\n\n\n\n

Interpupillary distance and adjustable eyecup<\/h4>\n\n\n\n

The eyecup is steplessly adjustable in height and lockable in any position, with index markings so you can find a previously found position. This ensures your eye's pupil is always in the same position relative to the telescope's exit pupil.<\/p>\n\n\n\n

That's more than comfort. A misplaced eye causes edge discoloration and shadows in the image. With a fixed, repeatable eye position, that problem is gone, even during long sessions.<\/p>\n\n\n\n

In your telescope<\/h4>\n\n\n\n

In a telescope with a focal length of 1200 mm, this eyepiece provides approximately 400x with a true field of view of about 0.15 degrees. For your own telescope, you calculate that using the field stop: true field of view = 57.3 x field stop divided by the focal length of the telescope.<\/p>\n\n\n\n

The effective field stop of this model is 3.2 mm. That number determines how much sky you actually see, not just the focal length.<\/p>\n\n\n\n
