I was considering trying a monochrome version, what do you think?
 
Looks nice, how many exposures is this made of?
 
Haven't tried this technique yet, out of interest how long was the shutter open for and what apature? Need to have a play with my shutter release.
 
It was 45 minutes of consecutive 30 seconds exposures, then stacked.
ISO-400 I believe and f/3.5
 
Is it just me, or are the stars slightly out of focus? Or did you do that on purpose to bring out the colors?
 
I didn't really do anything to this photo. I just focused to infinity manually and shot, it is possible the focus shifted or something throwing the out of focus with a narrow dof f/3.5
 
I can't really tell if you did or not, but apparently some good tips for star trails are:

-On the penultimate exposure, shine a torchlight onto the foreground objects to bring them out a bit.

-On the last exposure, leave the lens cap on. The black frame should help reduce some noise when you merge them together.

Well that's what a magazine told me anyway :p
 
I think I might light paint if I had different foreground but for this I wanted the silhouettes of the trees,
thanks for the tips
