These eyepieces were pretty cheap on Ebay, so I thought I'd buy a couple to check them out.

I got an Orbinar 17mm Super Wide Angle for $34 including postage. I compared it to my old Meade 18mm SuperWide Angle, which distorts slightly at the edges, and the Orbinar was very similar but did distort slightly more at the edges.

I also got an Orbinar 30mm Plossl for $24 including postage, and compared it to my Meade series 4000 32mm Plossl. Again, there was slightly more distortion at the edges. This 30mm Orbinar is better than a 32mm plossl I paid $95 for at York Optical a decade and a half ago

I notice Seben also sell the 16,19 and 27 mm Orbinar flat field eyepieces that everyone else sells, but often considerably cheaper, and I suspect that their SWA eyepieces are probably the same as those sold by other dealers at dearer prices.

I guess that if it was 20 years ago, when we were paying exorbitant prices for Meade and Celestron eyepieces, something like these Orbinar eyepieces would have been a godsend. But today they are ho hum.

Any thoughts?
Cheers,
