L-O-A 1.25", 21mm eyepiece

This eyepiece complements the set 3D eyepieces L-O-A. If you want to observe a very bright object, such as the moon, or want to use the two eyepieces for daytime observation with the binoviewer, the Lederman Optical Array (LO-A) will interfere. Simply replace the eyepiece with the L-O-A element with this "neutral" eyepiece.

With the set 3D eyepieces L-O-A and this eyepiece, you are flexible. Use the 3D effect on deep-sky objects such as star clusters and galaxies or the two eyepieces without the L-O-A element for bright objects.
