Description: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.

Meade Modified Achromat 40mm
I bought this as a star party alternative to the 30mm Ultima. Apparent FOV is tiny at about 34-35 degrees. Contrast is decent after I blackened the lens edges and barrel interior. In terms of sharpness, it works well with >f/7 systems, don't try using on focal ratios shorter than this. Eye relief is generous but the blackout problem doesn't appear to be as bad with this as some 40mm Plossls I've looked through.
