M76 is a small planetary nebula in the constellation of Perseus. Like
its big brother M27, it gets its name from the obvious lobed appearance of
the shells of gas coughed off from its parent star. At only about 2
arc minutes across, M76 needs a lot of focal length to photograph well.
This particular image was shot at f/6.3 or at about a 1,500 mm focal length
and has been rather drastically cropped. I'll most likely go back and
revisit this object at f/10 to better reveal the detail of the nebula.
