Triangulum Galaxy - M33

I have been trying to image the Triangulum Galaxy for over a month now but I was finally able to get some images over the last week.  The Triangulum Galaxy (M33) is a spiral galaxy approximately 3 million light-years (ly) from Earth in the constellation Triangulum.  It is the third-largest member of the Local Group of galaxies, which includes the Milky Way, the Andromeda Galaxy and about 44 other smaller galaxies. It is one of the most distant permanent objects that can be viewed with the naked eye.  Although it can be viewed with the naked eye, it is relatively dim and diffuse which means a small amount of light pollution makes this object very difficult to find.

The galaxy is the smallest spiral galaxy in the Local Group and it is believed to be a satellite of the Andromeda Galaxy due to their interactions, velocities and proximity to one another in the night sky. [source: wikipedia]
