what settings did you use???
i`ve wanted to try this for ages and have even picked out a few spots that have no light pollution….hi dave
settings are:
tripod
cable release with lock function
set my lens to infinity
set camera to burst shot mode
set to manual.exposure to 30″ using aperture, iso, and shutter (final setting iso320, aperture 5.6, shutter 30″)
30″ exposure approx 77 shots
used photoshop to merge each shot using lighten layer.make sure your camera and lens are acclimatise to the environment as you can get fogging on the lens front
and its a curse to get it clean.hope this helps

Cheers Philip…. i must get out soon for a crack!!
Could the same not be achieved with a single exposure?? or even 2!! one for the sky and one for the ground??I could prob do with getting a battery grip before trying this type of shot :roll:
you can do it with a single exposure but you may get digital noise build up on the image depending on the length of the exposure.
a battery grip is a good idea, i have one myself.
here a link to doing star trails hope it helpshttp://www.danheller.com/star-trails.html
very interesting link Philip!! thanks for that 8)
cant wait to give this a go.. :DNot a bad effort Philip. Its something i haven’t tried….yet.
My obversations are probably obvious to you.
The boulder is underexposed – and perhaps too central in the frame. I’d go landscape aspect – get down lower – and move the boulder to the left or right – while having the polar star in the opposite corner.
Before you start – either manually fire a handheld flash or a torch at the rock to light it up. test the exposure as to how many flashes you would need. Then do this at the end of the ‘long exposure’ – or towards the end of the last one if you are stacking.
You can easily walk up close during a long exposre and you won’t be visible in the image.
Other PI members could perhaps give you more solid tips – but this is what i have read in a magazine on the technique.

cheers brendan, its a tree by the way :lol:
i have had done the pre flash exposures, but for what ever reason when up loading to flickr it darkens the shot.
looking at home the tree is clearly visable (calibrated monitor),
at work its way to dark (uncalibrated monitor).
goes to show that everybody will have a different view.cheers

love this one Philip 8)
have you tried painting with light????
I read about it in a mag and im busting to try it…..not yet dave,
must get some led lights and large flash lamps and some colour filters
