I've never done anything specifically to ensure the stars' colors would stand out. Here are three I've done:
<http://www.sherb.org/startrails/> Although my trails don't "pop" like those in the astropix image, the color is noticeable. Each image was captured on Fuji Superia 400 with a Vivitar Series 1 19-35/3.5-4.5 (wide open) on a Pentax ZX-M. The first image was around six hours facing south, the second was around 60 minutes facing north (a porch light unintentionally revealed the foreground, but it's not bad), and the last was about five hours in the same location. You'll notice the sky beginning to lighten as dawn approached. I was disappointed in the lack of sharpness I got in these images. (These scans of 4x6 lab prints actually make the problem worse.) I haven't yet had the opportunity to try to figure out the cause, but one reason may simply be the the low acutance of the film. Perhaps a slower, finer grained film would render sharper images. I suppose stopping the lens down to f8 would help, too. t On 7/8/04 9:24, Kevin Waterson wrote: > This one time, at band camp, Norm Baugher <[EMAIL PROTECTED]> wrote: > >> Awesome site Dan, thanks for sharing. >> Norm >> >> Daniel J.
