Hell, I'd just try leaving the camera open longer first. You should have seen the brilliant array of bright R/G/B hot-pixel speckles before the ACR conversion went "POP" and made them all disappear. I'm sure stacking would work better, but I'm doing this for fun, not as a "project". I just revamped the image here with the brightness slider on the "blue" ramped down a bit... seems to help to make the stars stand out more: http://charles.robinsontwins.org/photos/2009/IMGP6866-3.jpg (EXIF info is in there, too, if you want to peek) >> >> 12.5 minutes later (oops! longer than planned), I have a >> slightly-overexposed photo of the sky (full moon that night) with the >> nice swirly circles going around Polaris.
