Hi forum,
Can anyone identify this lens? (see attached pics).
I purchased this lens (thru the internet) in a vane hope to improve my Tasco 114mm reflector. All I know is it's a 1.25" and supposed to be a plosyl lens. I hope to be able to use it with my forthcoming purchase of a 10" dobsonian reflector

. How does it rate.
Any info much appreciated
Richard
