It's the 'Cardboard Carton Tube" special. Looks like one of my experimentals from out of the workshop. I'll take a pic of my Binoc lens Finder scope ( if I can find it !! )
So here is the challenge ... !!!
Make a working telescope from junk and post a pic ... if you dare.
Not allowed to spend more than $5, higher points if you spend nothing.
just for fun
