Re: Eyepieces, filters, and such

Thanks for the suggestion. My eyepieces are indeed 1.25".

The page you mention sounds a little scary when it makes claims like
this: "Amazingly, when a major publication tested what was purported to
be a new planetary ocular, our orthos were not included in the
comparison test. Well, I think by now everyone is familiar with the
term 'media bias.' We have been fighting it for years and years."

And this: "My long personal relationship with the owner assures that we
receive only the best of the best." (What if the owner and UOptics get
into a tiff over something? Will they then sell substandard optics?)

Is University Optics trustworthy and are their products high quality?
Is there really a bias against them?

Cheers! --M
