This is a photoblend of 91 X 30 second exposures using the brilliant
Startrails photoblend action that you can download from here www.schursastrophotography.com/software/photoshop/startra...
This is the 45 minute storm in one shot - in other words it's the opposite end of the spectrum from the timelapse version I recently posted here www.flickr.com/photos/geoffc/2482761152/
The large white streak in the sky is the moontrail, the little ones are startrails. The long lines sweeping across the sky are planes taking off and landing and the ones on the water are fishing trawlers.
A curious thing in this image. There is a clear section of cloud above the main lightning strikes versus the blurred cloud around them. I think this is the result of these clouds being flashlit by each of the 20 odd lightning strikes whereas the other clouds were lit evenly by the moon in each image and hence blurred in the blend (hope that makes sense).
Taken off the cliffs at Bundeena, Royal National Park, Sydney Australia.
