Kaleidocosmo is an artistic astronomical mosaic made by Paolo Palma, an Italian amateur astronomer, that can reveal how much the starry sky is definitely more colorful than we can imagine. It shows the colours of all the stars visible to the naked eye from Italian latitude (Naples), photographed one by one with a smartphone as they appear through a 18" dobsonian telescope. 1250 snaps, that is 1269 stars if we also consider the multiple ones, including almost all the ones within magnitude +5 and several others weaker but with beautiful scarlet shades, such as the famous carbon stars. Paolo has put every star out of focus to make their nuances clearer, and finally stuck them to each other in scale according to their apparent magnitude. He has named it "Kaleidocosmo", because as through a kaleidoscope it is possible to see countless transformations of colored shapes, so through this mosaic it is possible to catch at a single glance the innumerable shades of all the stars of the celestial vault visible to the naked eye! Kaleidocosmo is the only mosaic in the World where it is possible to do this! After it, the starry sky resembles an immense bunch of fragrant flowers or a casket full of precious stones. Stars' colours are definitely visible already with naked eye, although most of them become visible or more brilliant through telescopes, they are the first visible trace of the different stellar spectrums, and are - almost - the only case in which the deep sky is truly "visible in colour". So these colours are what you can really see through a large telescope!
