Comet P9/Tempel 1, June 4, 2005, 10 five minute luminance
exposures, binned 1x1, STL6303E. Note change in comet position
(upper right) over the approximately 1 hour of exposure time. Also
note magnitude 11.3 galaxy NGC 4910 (lower left) and magnitude
16.6 PGC 44474 a bit to the right and below of center.

30, 2005, 10 eight minute
luminance exposures, unguided,
using the ME's variable tracking
rate, binned 1x1, STL6303E,
RCOS 16 @ f9. Note change in
comet position evidenced by
star trails over the
approximately 85 minutes of
exposure time. 95% humidity
during exposures. Alignment
and combination done in MIRA
AP.

Comet P9/Tempel 1. Left, pre impact on July 3, 2005, and right, post impact
on July 4, 2005. Both a single 5 minute 2x2 luminance image, with dark and
flat subtraction as the only processing. Weather didn't permit more images.
