    You can't. First, you're talking about seriously inferior glass and manufacturing in the magnifying glass. Also, it's not coated, so reflection and distortion in bright light will be a problem. Finally, the lens is ground so that the focal length enables you to hold it close to the object and make it appear bigger. All these points argue against a magnifying glass being used as anything but.

    Yeah well, Mike, the focal length would definitely kill any telescope possibilities, but I reckon you could use a single convex lens from a magnifying glass to make a rudimentary camera. The exposures would of course be woeful, but it would be possible. Actually the most rudimentary camera uses a pinhole, no lens at all.

    Of course, you're right. Even as I was posting it I thought of the pinhole camera. I stand with you, though, that the resulting images would be abysmal--probably due the quality of the glass and the lack of coating. The pinhole, in fact, might produce BETTER images.
