    Paul >>> As I understand it there are two methods:

    (a) single frame, long exposure

    (b) multiple frame short exposure + stacking (needs special software)

    Here’s a link for the basic way of doing the simple, long exposure method:

    What service you get at CPS! I was just looking up Chris Nocturne’s website address and Ian’s answer appears!

    Chris gave us a very memorable talk http://www.noctography.co.uk/

    In the picture referred to above the author has made sure that the pole star is behind the light of the lighthouse so that the start trails appear rotate as you see.Tthe light on the lighthouse is well over exposed because it will have been on a few times during the long exposure. He may have needed a flash or two to light the foreground.

    Steven Pepper did some nice shots in the dark using a flashlight and coloured gels to “paint” the scene. One that he shot in the car park under the library won best image in the 2009(?) L&CPU Knock Out. Ask him about it.
