First effort at processing and animating images from tonight's 2005 YU55 flyby, one tracking the target and the other at sidereal rate. http://www.slas.us/gallery2/main.php?g2_itemId=68&g2_page=7 Hopefully better versions will replace these if I can develop a better technique (I'm happy to supply the original FITs to anyone wanting to give it a try).

Those look damn good to me, Patrick. Well-done, and thank you! I'm hoping Keck got some decent imagery. I tried the links Rodger sent out in yesterday's SLAS blast, but none of them worked for me.
Wow, both versions are great, Patrick! ________________________________ From: Patrick Wiggins <paw@wirelessbeehive.com> To: utah astronomy utah astronomy listserve <utah-astronomy@mailman.xmission.com> Sent: Wednesday, November 9, 2011 1:24 AM Subject: [Utah-astronomy] 2005 YU55 animations First effort at processing and animating images from tonight's 2005 YU55 flyby, one tracking the target and the other at sidereal rate. http://www.slas.us/gallery2/main.php?g2_itemId=68&g2_page=7 Hopefully better versions will replace these if I can develop a better technique (I'm happy to supply the original FITs to anyone wanting to give it a try). _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php
Pretty good versions. How much time was supposed to have elapsed in those sequences?

Thanks Mike. I just wish I could get the background to be less washed out. But then I was shooting with the nearly full Moon nearby so maybe that's the best one can expect. I've got a few hundred 1 second exposures and am trying to figure out how to post those (they look a lot better). They show the target entering the field and then being "locked on" when it reaches the center of the image. It then stay with the target as it crosses a couple of FOVs.
How much time was supposed to have elapsed in those sequences?
About 5 minutes. Cheers, patrick
2005 YU55 is pretty much old news now but I was determined to come up with better versions of the flyby animations I posted the other day. Thinking back to stuff I heard about from Jerry and Tyler I was able to use a histogram to clean up the first versions. Still not perfect but I think they look quite a bit better now. Plus I was able to post slightly larger versions. In addition to the 5 second exposure sequences posted before I also added a couple of sequences using 1 second exposures. I think I like them better because there much less trailing. As before all sequences are at the bottom of: http://www.slas.us/gallery2/main.php?g2_itemId=68&g2_page=7 And for my fellow Mac users out there, I came across a nice bit of freeware that made assembling the individual frames into animated GIFs a snap. It's called GIFfun. Easy to install and operate and, to quote the late Mr. Jobs, "It just works." :) Find it on this page: http://www.stone.com/Download.html patrick On 09 Nov 2011, at 01:24, Patrick Wiggins wrote:

Your second effort was a vast improvement, glad you made the effort. I prefer the 1 sec exposures because it shows the movement against the background of stars. Which movement was incrediblely fast.
