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.
All told, from telescope setup time to final processing, this photo took roughly twelve hours to produce.
