I've always wanted a good piece of glass....ever since I saw my schoolmate's Celestron in the early 70s. I never got to look at the stars with it.....he only brought a table mount to school with him. But it was a fantastic spy glass.
This says 4.5 in.......I believe my friend's was 10 in. It was the size of a small snare drum.
Back then you needed charts, tables, a clock .....to manually adjust mount........to find a target object(star).
And it really impressed the hell out of me. I believe it was a lot more than a thousand dollars.....in today's money.
I'm not sure if this enhanced field feature......is actually from the scope.......or from a library and overlaid.
