Dean, Those are awesome! Thanks for sharing. The star party animations are really dramatic with the Milky Way star clouds rising in the background. I'm wondering what steps you used to create the animations? I have a sequence of 99 shots of early evening setup from TSP, but when I started to put them together in PS I realized my method would probably take a huge amount of time so I gave up. Maybe you know an easy way?

All were shot with a Canon 20Da used with auto dark subtraction. First up is non-astronomical... It is a sequence of the Warm Springs Fire on the north rim. It was shot with an 80-200 Canon zoom, set to about 100mm focal length. The timer was set to 1 exposure per minute, and 50 exposures are included (tripod was kicked before the 50...): http://alice.as.arizona.edu/~ketelsen/Animation_Warm_Springs.gif This is the one that started it all - shot on saturday (17 June) with a Nikon (yes-Nikon! w/$20 E-bay adaptor) 16mm F/2.8 full frame fisheye shot wide open. 30 second exposures (ISO 1600) every 2 minutes: http://alice.as.arizona.edu/~ketelsen/GCSP_MW_Animation.gif This sequence was taken sunday night (18 June)- smoke from the Sedona fire is seen low in the east. Shot with a Nikon 8mm fisheye wide open. @ minute exposure every 4 minutes. Note what looks like a Iridium Flare (not predicted by Heavens-above) in one freme in Hercules near the zenith. You can also see me smooching with girlfriend Melinda in more than one frame: http://alice.as.arizona.edu/~ketelsen/Animation_8MM_Milky_Way.gif After the first star party sequence, I wanted one that was smoother, yet went longer. This one uses 99 frames - 40 second exposures with the 16mm @ F/2.8 every 90 seconds, so covers 2.5 hours of the star party. Scopes visible are Joe Bergeron's 6" refractor to the left, Elaine Osborne's Newt at center, and Dennis Young's 28" at right. For those of you there, I set up to shoot thru the fence adjacent to the bathroom path - bathroom was the source of the red lights. This is a "slow" version - the "fast" one was just to frenetic going thru so many frames so quickly: http://alice.as.arizona.edu/~ketelsen/Milky_Way_2_slow.gif Sorry some of them are a little large - could probably have saved the jpegs at lower resolution, but I don't have the time to spend further on it. I hope you enjoy! -Dean -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list. -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
