Mauna Kea Images
The Tempel1 comet is caught here against a background of stars (with two especially bright ones) as it crossed the sky passing in front of the Virgo constellation.
The two circular structures around the bright stars are due to internal reflections in the optics of the instrument. Numerous background galaxies are now visible on this image. - CFHT
Color image of comet Tempel 1 against the background stars in the constellation of Virgo. The images were taken over a period of 15 min on June 29 at 20:10pm HST. The MegaPrime/MegaCam (36 CCD, 18Kx18K pixel camera) with a 1 square degree field of view was used. The exposure is a composite of a 150 second g' filter and 150 second i' filter.

This color image was obtained by stacking several exposures obtained in two independent filters. The elongation of the comet "core" as it appears on these images is due to the slow proper motion of the object against the fixed background of stars from our own galaxy and distant galaxies, on which the telescope was tracking during the set of exposures. The images were taken over a period of 15 minutes (taken on on June 29th, 2005 at 20:10PM HST), enough to cause the apparent elongation of the comet's core.

This is a series of images taken at the CFHT (Canada France Hawaii Telescope) equiped with the Megacam camera, pre- and post-impact. The images are 10s exposure time and were taken through the r filter. North is up, East is left. The field of view is about 11 x 11 arcmin, which corresponds to about 430,000 km at the comet. The increase of brightness after impact (which occurred at 05:52:24 UT as seen from Earth) is obvious on the second and third images.
