Messier 33 |

 | M33, the Triangulum Galaxy is part of the Local Group of galaxies, which includes the Andromeda Galaxy (M31) and our galaxy, the Milky Way. M33 is over thirty thousand light-years across, and more than two million light-years away. It is outstanding in good binoculars, but as its considerable total brightness is distributed quite evenly over an area of nearly four times that covered by the full Moon, its surface brightness is extremely low. Therefore, it is difficult to impossible to view this galaxy in telescopes which do not allow low magnification - lowest is best for this object !. This is a rather faint but large galaxy. The core is fairly bright and a large oval glow can be seen surrounding it. In a 8-inch at 81X, some hints of mottling becomes apparent. At 122X, the core seems to show several little pinpoints of light sprinkled throughout. The spiral structure cannot really be detected. |
