M45, the Pleiades, on January 25th, 2014
This is my second attempt at a guided shot of the Pleiades. I doubled the exposure time and took bias frames for the first time. Taken with a TMB92L, Canon T3i DSLR, Orion SSAG autoguider and 50mm guidescope, and Celestron AVX mount. Consists of 42 240-second light frames and 30 240-second dark frames, all at ISO 800, as well as 15 flat and 30 bias frames. Captured with BackyardEOS, stacked in DeepSkyStacker, and processed in Photoshop.
