Finally added some necessary equipment. This is my first try using SWSA 2i star tracker. Spent quite a while learning Polar alignment process. But imagine session was a breeze with automation that tracker brings. This is retake of M45 aka Pleiades with new equipment, just 52 min of total integration and a bit of processing. Equipment: Canon EOS T3i, Samyang 135mm lens at F2.8 and ISO 800. 124 X 25 second sub-exposures. #astropic
