About this image

Full-resolution comparison of inner coma on consecutive nights (2020 April 12th and 13th). 0.5 arcsec/pixel. See previously posted images.

Note the image on the 12th shows the first exposure of a star (brighter than in subsequent exposures) a little way to the east of the comet, not a fragment!

Stacked in AstroArt 7: alignment - 'star pattern + rotate' and 'follow minor planet'.

FITSWork processing: Iterative Gaussian Sharpening (8 pixels, 20 iter, 100% strength) as per notes from Nick James & Nick Haigh.
