Location: Fort McKavett, Texas Windmill was blown by 20mph winds from the south during entire exposure. High, fast-moving clouds moved through field, breaking up trails. Polaris is the bright point above and right of the windmill.
Kim: Actually, there is no satellite trail visible in this image. Polaris is also known as The North Star (is that what you were refering to?). Star trail images actually work best with slower film (Provia is a popular choice), but since I knew I'd need a higher aperture (f/8) to get the stars and foreground more focused, I chose the RG1000. Too bad they don't make it anymore.
Taras: I like your idea of a flash on the windmill, although I might try an incandecent beam to "paint" it instead. I'm going back to this location in March, so I may give this a try (an re-frame the shot as well).
Did you consider using a flash to illuminate the windmill's vanes to give it a bit more sense of motion? An interesting idea would be to position the camera so that the windmill and polaris are level on opposite sides of the image... two counterbalanced circles.
I see you use RG 1000. I should probably use some of my remaining rolls for some star trails, while I am guiding my piggyback Hassy attempts.
I like the addition of the satalite... this is the first star trail image with one I've seen. Reminds me of a space ship, really! hahahha A question for you.... is it true, the faster the film, the less time it takes to get long star trails? I tried some star trails in December with Velvia 50, just to try it out. Left the shutter open for 2 hours and when I got the slides back, it's like the stars didn't really move.
