40mm ST Series Plossl Scopetronics 1.25" Eyepiece, has a nice 44 degree apparent field of view. The eye relief length is not listed, but it is very, very comfortable. My guess would be 20mm. The interior of the barrel is blackened. Has flexible rubber eye guard and a textured grip area around the barrel. Including the the plastic bolt style case it came in, no end caps though as none came with it.
The condition is very good. The lenses are clean and free of any scratches. The barrel has some set screw marks and a small scratched area below the eyeguard.
This has been a great eyepiece for scanning and narrowing in on objects, also great on larger objects where less magnification is better.
