The Andromeda Galaxy (M31)

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. I then stacked the resulting images with Deep Sky Stacker and processed the composite image with Photoshop.
