I've always used relatively short eye relief eyepieces, Plossls, Panoptics, and Naglers, and never experienced blackouts (kidney beans?) until I bought (and,...
The article in S&T pretty well covered the issue, noting that in actaul use, the mounting is inadequate. Period. When that scope was first introduced, my...
In this vein I am trying to gather a list of Japanese manufacturer's symbols and company names. V in a circle is Vixen, still used. TS in a triangke is...
In the current issue of S&T, I just noticed an ad for Surefire flashlights. I suspect they won't sell many of them to astronomers, because they're clueless ...
