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.
