A Very Full M31
This is one of the better M31 images I have taken. It is 6 ten minute images at ISO 800 taken with my Orion 100mm F6 refractor and my Canon 300D DSLR.
The big spiral galaxy, M31, also known as the Andromeda Galaxy, is our closest major intergalactic neighbor. It is speculated that it is on a collision course with our galaxy, to occur billions of years from now. The two smaller elliptical galaxies are M110 and M32. They orbit around their larger brother M31.
M31 can be spotted by the naked eye very easily, but the sky must be reasonably dark. It is a large hazy patch about the same size as the full moon. This galaxy is located near the square of the constellation Pegasus.
