3-Element Eyepieces

These fine eyepieces offer the price-conscious amateur, an excellent alternative to more sophisticated and expensive optics.

The four Modified Achromatic focal lengths shown here are an optical advancement over the traditional Kellner and yield sharp, faithful lunar, planetary, and deep-space images.

• All 1.25" O.D. focal lengths are multi-coated.
• .965" O.D. are coated with magnesium fluoride (MgF2).
• The 40mm models of both barrel diameters provide well-corrected, wide-field images on any instrument, and with a moderate investment.
