Pinwheel Galaxy M33




One of the bright members of the Local Group of Galaxies,
and probably the nearest spiral galaxy after the Andromeda system M31.
Lies on the western portion of the constellation Triangulum.
18-22 November 2012.
41 exsposures but 10 minutes each stack in DSS.
Full calibration .
Was very bad "seeing" and fog around my house,
PS
Astronomical " seeing " refers to the blurring and twinkling of astronomical
objects.The Astronomical seeing conditions on a given night at a given location
describe how much the Earth's atmosphere perturbs the images  of stars
as seen through a telescope.
Seeing is one of the biggest problems for -Earth based astronomy.
