I spent a very pleasant afternoon with my son on very hot and sunny beach in Bournemouth, watching the air display. It was only in the evening we learnt that one of the Red Arrows pilots had crashed.

Crescent nebula

Crescent nebula, originally uploaded by ThinkingCamera.

NGC6888. This is a faint one, but very interesting. What you are seeing is an arc of gas excited (so glowing) because of the powerful “solar wind” of the bright bluish star inside the “crescent”. This is a “Wolf-Rayet” star (there is a good wikipedia article) – a massive and very bright star which pushes out its atmosphere in a powerful “solar wind”. The arc of gas was expelled from the star and energetic streams of particles are causing it to glow.
40 x 30s exposures. Atik 320e camera. f2 CPC800 telescope.

or more formally comet 2009/P1. This is my first image of a comet. This one is now showing a tail, the characteristic “greeny hue” but not much detail. Magnititude officially around 8.5 but it seems brighter than this to me.
