Comet 103P/Hartley near Cr62

Left Image, False colour representation of 103P on 19-10-10 to enhance coma and tail structures.

Comet 103P Hartley near open cluster Cr62 (Image below, bottom Left) Click to embiggen for open cluster goodness.

The comet appears as multiple images as this is a stack of 3 x 60 second exposures in Global Rent a Scope GRAS 14 and stacked in Image J using Z projection of maximum intensity and a bit of contrast fiddling.

A chart of the region identifying objects in the image is next to it, the big rectangle is the grame of G14 (again, click to embiggen).
