Registar says 68,200

A number of people have asked me how many stars appear in the Cocoon nebula 3-frame mosaic.  I use a program called Registar to link separate frames together so I can see how they all fit – and Registar will also do a “star count” for the stars in the image (I don’t think it is accurate to the level of a star 🙂 )  Anyway – Registar says there are 68,200 in this image – always turns out to be a LOT less than you would guess.
