The green or cyan Comet PanSTARRS passing above the Double Cluster in Perseus on January 25, 2020. This PanSTARRS (one of many!) is C/2017 T2. The star cluster to the left of the comet is NGC 957. The loose cluster in the bottom left corner is Trumpler 2. This is a stack of 8 x 4-minute exposures at ISO 400 with the Canon EOS Ra on the SharpStar HNT150 Hyperbolic Newtonian astrographic reflector at f/2.8.
This is Comet Wirtanen 46P in Taurus on December 14/15, 2018 accompanied by a Geminid meteor, caught by chance of course. Yellowish Aldebaran and the Hyades are at left, the pink California Nebula (NGC 1499) is at right, in Perseus, while the blue Pleiades are at centre. They form a nice colour contrast with the cyan-green comet. The Taurus Dark Clouds of interstellar dust are at top. Comet Wirtanen was two days before its closest approach to Earth and nearly at its brightest. It was visible to the unaided eye. I got a chance to capture this and other views after Chinook clouds cleared off near midnight on Dec 14/15. This is a stack of 5 x 2-minute exposures with the filter-modified Canon 5D MkII camera at ISO 800 with the Sigma 50mm lens at f/2.8. The meteor is from one of those frames. The camera was on the Star Adventurer tracker.
Comet Wirtanen 46P with the star clusters of Taurus: the Pleiades (M45) at top, the Hyades with yellow Aldebaran at lower left, and NGC 1647 at far left. The comet was nearly at its closest point to Earth and at its brightest. This is a stack of 6 x 1-minute exposures with the Rokinon 85mm lens at f/2.8 and Canon 6D MkII at ISO 1600, on the Star Adventurer tracker, taken December 14/15 as the skies cleared in the Chinook winds of southern Alberta. Star glows added with Orton effect in Luminar.
