Not too many clear nights this month but enough to get some pictures of Comet 2014 E2 Jacques. The comet is well placed for UK observers but doesn't look that impressive through small telescopes. It's great that such an unimpressive comet is attracting media attention ;-)
Comet Jacques is moving rapidly across the sky. The problem with taking pictures is that I've been limited to exposures of just 2 minutes through the DSLR on the telescopes. More than that and the comet smears across the image. The middle picture above was an attempt to autoguide on the comet - forcing the telescope to track the motion of the comet rather than the stars. Unfortunately the weather wasn't good that evening but the method worked.
The movie above was compiled from 29 two minute exposures collected on the evening of August 28th. The rapid motion of the comet makes a nice (if short) movie. Comet Jacques was moving at about 37 km/s and was about 84 million km from Earth. It was shining at around 7th magnitude.
I'm hoping for a clear sky tomorrow as Comet Jacques sails past the Garnet Star in Cepheus. Should make a nice photo with contrasting colours.
