For sale in the netherlands. Widefield 2 inch eyepiece. This is a modified eyepiece from a military gun turret visor. It has a focal length of 30-32 mm and a field stop of 36 mm, and about 60 degrees apparent field. It is multicoated an yields razor sharp images to the edges of the field,
The eyepiece has two drawbacks
1) it needs about .7 inch more in focus than most 2 inch eyepieces, but this can be easily modified mechanically
2) it is heavy, about 2 pounds
reasons for selling: My new 300mm F4 telescope yields using this eyepiece a 7.5 mm exit pupil which is too much for my (medium age) eyes.
Asking 200 euros plus shipping (1 euro is about 1.19 dollar)
