telescope eyepiece f=40mm, 30mm eye-relief:
I am selling partialy my collection of eyepieces because there are too many close focal lenghts.This one is a 40mm focal lenght, 30 mm eyerelief, very luminous, no fugus or dust between the lenses. It have some surface scratches on the inside lens but does not affect in any way the viewing. They are not seen when looking through the eyepiece.It have no false reflections, it displays a flat field and it is sharp to the edge on a 12" newtonian. It have a built in field stop, so I think the person who adapted it to astronomy have some experience in this field.I have bought it like you see it in pictures. It is a brass mounted optics and aluminium 2" fixed adapter.I suspect it is an old military eyepiece adapted for astronomy because I found a picture on Wikipedia with an eyepiece which looks like the brass part from this one. l Could be Zeiss but it has no markings. I know that Zeiss manufactured almost all optics from WW2.Please see my other eyepieces that are for sale.
It is automaticaly relisted. In the meantime it received a polished finish. I have attached new pictures.
Please let me know if you are from Russia or Ukraina because I found out (on my expense) that Romanian post have a higher price for some countries. Maybe there are other too. I will check individually. Thank you for understanding.
