Back Garden Star trails

Experimented with the 50mm lens for star trails and it looks good. This was just in the back garden and there's a lot of light pollution around here but there's a mass of stars been picked up. With the 50mm you also need less shots, this is only 20x30s exposures and it's a decent length of star trail, 40 shots (20 minutes worth) would be more than enough.

Now, need to get out and get a decent subject...
