That’s a great shame – I hadn’t seen that painting before (maybe we never now will see it!). It is Donati’s Comet as you can see Arcturus near the head of the comet.There was a Donati’s Comet painting from the Paul Mellon collection by William Turner of Oxford on loan at the Royal Academy, next door to Burlington House a few years ago. It was an almost exact representation of the stars in Bootes and in that case Arcturus was comingled with the head of the comet. You could easily see the star on the original but it was a lot less obvious on any copy of the painting. (see Slide 17 at: http://britishart.yale.edu/collections/highlights/prints-drawings
