I noticed on Guide 9.0 that 50P/Arend was very close to Neptune today,
so took an image! Comet is arrowed at around 16th mag. Neptune dead
centre. The faint trail of stars just above the comet (20th mag?) are real
and appear on the STScI DSS images of the field, even though they look
like hot pixels.

Of course, Neptune is around 20x further from Earth than the comet.
