Now THIS is cool! Reminds me of some of Bryan Peterson's work. He does swirly stuff like this.

I've seen these done before, but seldom with such a great foreground. Congratulations!

What I don't understand is all the different colors of the stars and planets...? I cannot remember ever seeing red or green, purple or blue stars!

Is this the result of exposure-stacking where you colored each exposure with a different filter?

G'day Walter S

All stars display the colour spectrum from the main gases that are burning, thus the differing colours seen in the photos

If you want to try your own star-trails via stacking, a neighbour of yours offers a freebie s/ware pgm to do it ... log into <startrails.de> and download your copy. I use it, and it's great

Regards, Phil

Very cool! I was trying to intepret the exposure information...what does 300 x 60 secs mean...18o minutesd? I am amazed that there is no visible noise!

300 x 60 sec = 300 minutes = 5 hours

No color filters, just the natural colors of the stars with a saturation boost before blending with the foreground layer.
