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.
Comfort, Quality, Value. The
Explore Scientific 52° LER Series mid-range focal length 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.
