This USED 25mm 1.25" Modified Achromatic Eyepiece is in good condition

These fine 3-element eyepieces offer the price-conscious amateur an excellent alternative to more sophisticated and expensive oculars. 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; eyepieces of .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.



Design: 3-element Modified Achromatic (1.25": multi-coated; .965": MgF2 coated)
Focal Lengths: 9, 12, 25, and 40mm
Eyepiece Barrels: 1.25" or .965", threaded for filters
Apparent Fields (approx.): 40°
