The photo above appears to show the gibbous Moon captured in the hands of an observer. Actually, our lone satellite is seen here projected through the lens of an 80 cm (31.5 in), f/8 telescope onto a piece of tissue paper, instead of using an eyepiece. This interesting projection allows many observers, rather than just a single viewer, to see the image coming out of the telescope. It also nicely demonstrates the real field of view of a telescope, which is larger than what an eyepiece can cover. Photo taken on August 18, 2011 from Casa del Romano, Italy.
