Aw thats a shame........
what about bino's, same setup.............
or if you really want to be a star in all your visitors eyes,...get a dark room with a window on the sunny side and put some cardboard up in the window frame.......drill a hole in the middle, say 1/32, and so on, until you get a great image off the light coming through the hole........
Most of the time, the smallest of holes works best I would say 1/16 or sometimes less.
You will have the biggest pinhole camera in town!!!
Great way to watch sunspots, as long as the wall on the other side is far enough away to project a decent size image.
I am also using a CCD video camera..... lens looking through some welding glass, and stopping the Iris down and lowest gain etc etc......works great for sunspots as long as you can loose enough light and zoom in enough.
I used to often look at the sun using the projection method with my 8" reflector, using aperature plates over the end....
many ways to skin the old cat as long as you are careful I suppose.
I just love a challenge, working against the odds
cheers
