I had the opportunity to try my hand at Star Trail Photography on a recent holiday in the Lake District. I decided to take 6 five minute exposures and blend them together in Photoshop using the 'lighten' blend mode.
I converted the finished image to black and white as shown below. I made a few mistakes but then this was pretty much my first image of this type so overall I'm just pleased that it came out at all.
This is Castlerigg stone circle near Keswick, Cumbria. UK
