Details:
Here's my second attempt at imaging the Andromeda Galaxy. All told, from telescope setup time to final processing, this photo took roughly eight hours to produce. The Andromeda Galaxy is 2.5 million light-years away. A single light-year is 5,865,696,000,000 miles. Now multiply that by 2.5 million. That's pretty far away. It contains roughly 1 trillion stars.
Taken with a TMB92L, Canon T3i DSLR, Orion SSAG autoguider and 50mm guidescope, and Celestron AVX mount. Consists of 53 120-second light frames and 41 120-second dark frames, all at ISO 800, as well as 15 flats. Captured with BackyardEOS, stacked in DeepSkyStacker, and processed in Photoshop.
