This completes my April 1-2 imaging session imaging 4 comets. Here is the widefield C6 HyperStar setup covering an area in Virgo. The night was exceptional yielding a FWHM of ~2.2 across the stacked field. Comet 62P/Tuchinshan is estimated to have faded to 12th magnitude but certainly appears brighter here.
