M57 with ToupCam

A test of my new ToupCam with Newtonian 6" f5 telescope. Only 10 exposures of 15 seconds each, with far from perfect seeing, and I got down to 18th magnitude stars (the two circled stars) - pretty impressive! So we can see stars 60,000 fainter than with a naked eye. Another interesting number - the whole sky contains almost 240 million stars brighter than the 18th magnitude. These stars are 35 times fainter than current Pluto (14.1m), and 2.5x fainter than the Pluto's satellite Charon (currently 17.0m).
