Comet C/2021 A1 Leonard on 2021 December 22 at 11:40UT.
using a Canon 6D + Sigma 200mm lens. 10x30sec. FOV 10 deg. North below. Image taken near Tailem Bend, South Aus.
Naked eye estimate 4.0.
Through 25x100mm binoculars, the comet is a superb sight, with a star like nucleus embedded in a parabolic hood. The first 1.5 degrees of tail (dust) is quite bright. The ion tail is very difficult to view visually as it shines by fluorescent light in the blue spectrum, but easily captured in photos. In this image, the ion tail is greater than 10 degrees long. Note the disconnection about halfway up. This is a common feature with ion tails, snapping off the nucleus, which then get carried away by the solar wind
