Hi All,
I have been following this thread on CN.
http://www.cloudynights.com/ubbthrea.../o/all/fpart/1
It started about the Masuyama eyepieces and has got a lot about many older type eyepieces. Orthoscopics etc.
If your looking for some history and links to your not so normal type eyepieces follow this thread on CN.
Worth the read.
Thanks to those who posted on CN for some wonderfull insight on eyepieces.
