Sky at Night

April 24_25 2011. Volcanic ash star trail :-) Iceland's Grimsvotn ash arrived in UK skies overnight. Did it affect the sky visually? Quite possibly, although density levels were low. Possibly more reddish/blueish than normal? Nicely captured the opposing curvature either side of the celestial equator. Oly E5, 7-14mm. 15s exposures @ F4 ISO 500 shot continuous through night (1000 exposures). Paint lit the foreground and even the growler got in the shot :-)
