Taken looking south to Wollongong from Providential Point, Royal National Park, just south of Sydney Australia.
This is my first attempt at a multi-exposure blend. This image is a combinations of 57 X 30sec exposures using the fantastic Startrails Photoshop Action that you can download free from this excellent site:
I was put on to this action by Dave Burrow whose amazing startrails image can be seen here:
The brilliant thing about this PS action is that the longest exposure you need to take is 30sec and so it virtually eliminates the noise problem of conventional long exposure startrails. You can imagine how much noise this shot would have as a 30min exposure.
The straight lines are some of 9 planes that flew through these exposures over the half-hour I was taking them – amazingly consistent flight paths. It got so busy I had to delete some of the planetrails, hence the little gaps in the startrails.
