Identify

[wookie1965]

I got 3 eyepieces with second hand scope a SR4mm i`m guessing that is a basic eyepiece but i also got a 10mm and 25mm plossl which i`m stumped on  can anybody identify them please.

Look like these.

Yes very similar except writing is at the top of the eyepiece i think they could be a variance of these thank you.

They were the standard Chinese / Taiwanese plossl supplied with scopes in the 1990's. They are quite nice to use - better than the 3 element eyepieces supplied these days.

The SR4 is not great to be honest with you. The one I had was a 2 element design that worked OK (just about) in a long refractor but was pretty poor in faster scopes (eg: F/6, F/8 etc).

Yep, as John rightly says these used to be supplied with the early evostar telescopes, antil skywatcher got wise to them being quiet good, so they bundled the cheaper ep`s instead, i rate them quiet well and they are very good for Luna  A-focal imaging
