oh, I am on a roll now, if you ignore the double posting! Had no idea this was happening until I went out to collect dh from the station at 11pm and thought the sky looked a bit iffy...
stopped to take a few pics and then was late for dh, and this one was taken with my phone balanced on a dodgy sign post, which is why the stars are lines....it was only a 14s exp so they're not real star trails.
Also green and red visible to the naked eye and lovely spiking pillars.
