M33, the Triangulum Galaxy, is the Milky Way’s little sister. The Andromeda Galaxy, M31, is the largest of the three sisters. And, both Andromeda and the Milky Way have satellite galaxies. Andromeda has a dozen. The Milky Way has two – the Magellanic Clouds.
M33 is quite faint, and it is an object that begs for dark country skies for a proper portrait. Below you see M33 as recorded from the light-polluted central Austin skies using the 130mm F/4.5 astrograph fitted with a light pollution filter on a moonless night. The image is the composite of 150, 60-second exposures. I really need to try to record this subject from Gila, New Mexico; sigh.
