NGC 3132, aka the Southern
Ring Nebula, aka the
Eight-burst Nebula, is in Vela,
and estimated to be about
2000 lightyears distant.

The white dwarf star that gave
birth to this nebula, and is
reponsible for its glow, is NOT
the star seen quasi-centrally,
but is close to it, though too
dim to be seen here.

This is a small object, but
some of the extended Ha shell
is nicely demonstrated -- also
note a faint blue glow around
some of the peripheral
portions of the nebula -- we
feel this is a real feature and
not artifact. Other recently
completed planetary nebula
images, including M97, show
a similar dim outer blue shell.
