P3D Re: 35mm viewer eyepiece

[Peter Abrahams <telscope@xxxxxxxxxx>]

Rini eyepieces are very well known among amateur astronomers, are very good
values, and generally give good views at a telescope.  But they are
assembled from surplus optics and are not the product of a lens designer
who optimizes each surface.  If you feel that an eyepiece at a telescope
can as well be used as a slide viewer, an x-ray viewer, a microscope
eyepiece, a magnifier, etc.; then these will be a good bet.  But if you are
very picky about distortion, chromatic aberration, etc., then regard the
purchase as a gamble -- an inexpensive gamble.
