** Price Drop ** Optolyth 70 x WW eyepiece

[vk6kb]

I have this Optilyth 70 x WW eyepiece that came with other gear I bought as a job lot.
I have no use for it so its available.
I know nothing about it other that what I can find on Google.
Yours for $250 incl post Australia wide, selling new for over $600 US
Cheers
Keith

It seems I made a spelling mistake as well Its OPTOLYTH

It appears to be about 43 mm outside diameter and I believe the thread is M37 x 0.75 pitch.
It came from a deceased estate and the owner was a research astrophysicist who studied supernovas.
Apparently he donated over $30k of gear to the Uni.
Anyway this was part of what was left.
If anyone is interested I can provide decent pics, but no more info than what Mr Google can provide sorry.
