Explore Scientific 30mm 52° Series Waterproof Eyepiece - A Review
Description
Loved by deep sky observers, a 30mm focal length eyepiece produces a large exit pupil which floods your dilated eye with light, which is needed to see faint galaxies and nebulae. Low power eyepieces are very important to observers for a variety of reasons: Their wide true field of view make object location and pointing far easier.; Many deep sky objects are large and are best viewed at the lowest magnifications your telescope/eyepiece combination can achieve. When seeing conditions are poor, objects will often still look sharp at low powers.
Explore Scientific Waterproof Eyepieces - Comfort, Quality, Value. The Explore Scientific 52° Series eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. With an apparent field of view of 52 degrees, these eyepieces offer incredible value in a very nice eyepiece. Expect exceptional quality, eye relief and value versus a comparably priced Plossl.
Another great benefit of these eyepieces is the excellent contrast and ease with which you can gaze, not directly at an object, but slightly to either side. This skill, called using averted vision, is especially helpful when observing faint objects, because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.
