Orion Explorer II 25mm
I picked one of these up [and a 20mm also] when Orion had them on sale for 'no worries' use w/ an inexpensive large f-ratio spotting scope at the range.

I've found that, at least in the OTA i'm using it with, it performs with near identicality to a plossl in the same $25 to $30 price range this normally sells for [and much better than a couple of $15 or $20 'ebay plossls' i got for use with the same scope].

This has become my eyepiece of choice. Between it and a 150 Plossl, I can barley tell a difference.

Nice low power eyepiece at a very good price. Works well with my 14.5 inch F/8 newtonian

The sharpness is pretty good on this eyepiece. It uses a modified kellner configured to yeild a 50 degree field and better sharpness. Only a tiny bit of image softening at the extreme edges. I detected no induced false color from this eyepiece. Very slight field curvature. Minor gripes aside, this is a fine, inexpensive eyepiece. Reliable performance and just about the best kellner I've ever used. Excellent antireflection coatings. Good job, orion!
