About this Object

The Andromeda Galaxy is a spiral galaxy approximately 2.5 million light-years from Earth in the Andromeda constellation. Also known as Messier object M31, it is often referred to as the Great Andromeda Nebula in older texts. The Andromeda Galaxy is the nearest spiral galaxy to our Milky Way galaxy, but not the closest galaxy overall. It is named after the mythological princess Andromeda. The Andromeda Galaxy is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum Galaxy, and about 30 other smaller galaxies.

About this Image

This is my first test image with a new autoguiding set up. No difficulty acquiring the target or getting focused, even thought it was just a few days before full moon. Started shooting at 1805 and captured 256 frames by 2130. Guide scope: Pronto 70mm f/6.9. Guide camera: Orion Starshoot. PHD Guiding. ZWO USB to ST4 adapter. Guiding just worked during the imaging session. On detailed examination, only five frames were rejected, and that was due to satellites streaks in the frame. The stars were consistently round in all frames, and there was little drift and no field rotation discernable to the eye, The guiding test was successful, but the overall result was disappointing due to the sky being washed out by the moon.
