Based on my short experience with the photography of star trails, I visited a local church the other evening – it is unique as it has a ‘twisted’ spire (which can be seen below) Not unhappy with the results – for the technically inquisitive 60 exp 20s at f/4 ISO 1600
We’re in the middle of the period where the Perseid meteor showers are visible (in fact the 12th of August is supposed to be the best night) so I may have to go out tonight…
