A versatile magnification range suitable for many deep-sky objects, such as star clusters and galaxies, as well as general lunar observing.

Low (D/3):
42x
(with a 6 mm eyepiece)

Low Magnification (D/3)
A wide-field magnification used for scanning the sky, observing large nebulae, and locating objects before switching to higher power.
