M33, the Pinwheel Galaxy
Lying in the obscure
constellation of Triangulum, M33 is the third biggest member
of our Local Group of galaxies, and one of only three true
spirals in the cluster. It has only a fraction of the size and
mass of M31, which is a fairly near neighbor both as seen in
our sky and in reality.
This was shot with my
lovely Astro-Physics 155mm refractor at f/9. It's one of the
few galaxies in the sky that appears large enough to fill the
frame with this much detail.
