This is my best-ever photo of the Andromeda Galaxy (M31) and its two companion galaxies (M32 and M110), taken back in September 2014, from the Paint Mines Open Space in Calhan, Colorado. I took this photo with a TMB92L refractor telescope, a Hutech-modified Canon T3i DSLR camera, an Orion SSAG autoguider and 50mm guidescope, all riding on a Celestron AVX mount. All told, from telescope setup time to final processing, this photo took roughly twelve hours to produce.
The Andromeda Galaxy is 2.5 million light-years away, and it contains roughly 1 trillion stars. It's the closest spiral galaxy neighbor to our own Milky Way and can be seen with the naked eye under extremely dark skies.
