ASTRO: 2005 YU55 The Movie

After finding the MPC elements were too far off and the Horizon's site
pummeled into submission I finally got good elements about 3 hours after
closest approach. This is a 3 minute animation, 15 second frames,
tracking the asteroid. Taken with a 14" LX200R @ f/10 using a
STL-11000XM binned 3x3 for an image scale of 1.5" per pixel. Sub frame
of 800x600 was taken to cut download time rather than download the
1336x890 full image. That meant matching darks and flats. Something I
forgot about at the time and delayed processing. Even then the download
time stretched the time scale to about 3 minutes time for the 10 frames
used to make the animation. Mount was a Paramount ME controlled by The
Sky 6 Pro and CCDSoft 5. That guy
was really hauling ...

A 1.7 meg download so wait for it to animate.

Nice effort, Rick. It must have been a bear trying to track that one.

Once I downloaded good orbital elements from the JPL site it was pretty
easy. The mount and computer did the hard work. I just started the
camera running and watched the data come in. Computer told the mount the
offset drive rates for both axes to follow the asteroid. It did a very
good job.
