Okulārs, EXPLORE SCIENTIFIC 52° LER 30mm Ar

A 30 mm focal length eyepiece creates a large exit pupil that floods your eye with the light needed to see faint galaxies and nebulae. Low-power eyepieces are very important for observers for various reasons: their wide field of view makes it easier to locate and point at an object. Many deep-sky objects are large and are best seen at the lowest magnification that your telescope and eyepiece combination can achieve. When viewing conditions are poor, objects often still appear sharp at low powers.

Explore Scientific 52° LER series medium focal length eyepieces are excellent flat-field multi-element eyepieces that can change your visual astronomy experience.

These eyepieces are an excellent choice for observers who wear glasses – they feature excellent performance and durability.
