With his SIGMA 135mm F1.8 DG HSM Art lens, Canon EOS Ra, a star tracking camera mount and loads of astrophotography experience, SIGMA Ambassador @babaktafreshi was able to capture this absolutely exquisite view of Comet NEOWISE in a single, 2-minute exposure. The SIGMA 135mm F1.8 Art is available for Canon EF, Nikon F, Sony E & L-Mount: https://bit.ly/sigma-135-art #sigmaphoto #comet #cometneowise #neowise #astrophotography #astronomy #nightsky #nightskyphotography #stars #starphotography」7月23日 22時29分
