A few snaps of All Saints’ Church, Cottenham, with the stellar backdrop of the Milky Way. In the third picture down, you can see the light trail of a satellite I spotted as I was framing up. Milky Way is perhaps most obvious in the last photo.
For those interested in such things, these were all shot with ISO set to 1600, a focal length of between 24 and 105mm and an f-stop of 4.0. Shutter speed was varied to accommodate the 500/fl rule, whereby you divide 500 by the focal length to obtain the maximum speed that will avoid star trails appearing as the Earth turns on its axis. At 24mm, a shutter speed above 20 seconds will clearly show star trails.
If some of these are not perfectly sharp or framed, blame my freezing hands, it’s minus F out there tonight…
