C/2017 T2 (PANSTARRS) 2020-May-24 Chris Schur

This 8th magnitude object in Ursa Major had just past its orbital plane crossing a few days earlier, and on this night made a magnificent composition with the bright triplet of galaxies M81, M82, and to the right the large diffuse galaxy IC2574. You can also see the yellowish background nebulosity of the "Integrated Flux Nebula" or more commonly called "The Galactic Cirrus" in the background. This shot was taken with our Sigma 150mm f/2.8 macro lens wide open and has consistently produced razor sharp images to the edges of the frame.
