Turns out that on many of my Halloween #comet pictures another celestial celebrity was included: Barnard's Star, at 6.0 light years the fourth-closest star to our Sun (after the three of Alpha Centauri), a Red Dwarf shining at a V magnitude of 9.5 mag. See https://astronomynow.com/wp-content/uploads/2018/08/Barnard-s_Star_magnitude-11_detailed_finder_chart.pdf for a finder chart but beware: #BarnardsStar is moving 10 arc seconds per year in the sky plane which is the highest stellar #ProperMotion known.
