Comet C/2013 A1 (Siding Spring) July 24/25
ED100 at F7.2, 90 x 1 minute subs, Pentax K-5. Something that looks like an anti-tail seems to be present.
Just a heads up if anyone wants a photo opportunity, the comet passes close to bright galaxies Fornax A and Fornax B on July 28/29. Not that it will be an easy shot as the comet noticeably moves against the background stars after a minute or two.
