When gear heads by eyepieces

They don't look though them, they take the out for "photo sessions!" La la la, la!!!

Astromart:

2. TMB Supermonocentrics 10mm and 16mm
Both are in pristine condition. Come with original boxes. The 10mm was bought new from APM just last month and was never used - only been out of box twice for picture sessions.

Whatever, these guys are terrific planetary eyepieces...

Are you damning them with faint praise?

Not at all, these guys are highly regarded by many folks who like to observe the planets, planetary nebulae or double stars, especially at high powers, even though they have a very restricted 32-degree field-of-view when compared to most modern eyepieces. See this...

.... and there are many others to be found, too.

So fantastic...they stopped making them due to lack of demand. But, if anyone is interested and you know a good machinist, you can always have barrels made and buy 10/20 scratch/dig triplet lenses from a good supplier and get something similar to the monocentrics.

I believe the main reason they stopped was because the designer and manufacturer, Thomas M Back, passed away suddenly in 2007. Keep in mind also that these are very specialized eyepieces and not very popular with the general amateur observing population, due to their very narrow field of view. Still, there are a lot of experienced observers who swear by them for high magnification views of small and dim objects, as they pass more light than just about any other eyepiece design.

As was I reading the S&T article I did a quick cost/benefit analysis and concluded that a larger scope with ordinary Plossls would be a better use of funds. YMMV.

Man has been BUYing and selling pretty rocks since long before you discovered Fox News.

Why pick on somebody who BUYs and then sells some eyepieces?

Psst. Anyone wanna BUY some really dirty eyepieces? ;-)

Because the rock serves no other function except to look pretty? Maybe a paper-weight.

LsD will probably drop in soon and weigh in.
