What is it worth?
I have never seen one at this focal length...Meade's ads don't mention one...is it old?

If you have a 20mm (Research Grade) Meade Wide Angle (not Super Wide Angle), it is indeed an old eyepiece. It is an Erfle and was well thought of in its time.

I have the Meade 20mm and 15.5mm Research Grade Erfle eyepieces I purchased new around 1980. That's probably what you have. These EPs were pretty hot stuff back then. They're great with scopes over f/7. Fast Newts show a lot of coma with these EPs. But contrast is excellent. Great "3D-like" views of nebulae and star clusters. Despite the poor edge performance, the generous AFOV provided some compensation. Mine saw extensive duty in my 16" f/4.5.

What's it worth??!! Take a look on these forums! Everyone's looking for the "holy grail" of eyepieces - myself included. If you find an EP that you like, well then I'd say it's "priceless!" [good luck in your quest!]
