This is an image of M67 an open star cluster in the constellation of Cancer. I wanted to give my modified SC3 Toucam a star test and this was a conveniently placed cluster. If you hold the mouse over the image you will get an inverted image that shows the amount of stars captured. I estimate mags of 16 to 17 with the 4-sec exposure. Image represents 60 X 4 sec exposures.
