March 17, 2009 between 19:01 UT en 20:07UT, 30 images of 2 minutes each were combined. The 10Micron mount was tracking the comet by the orbital elements that were uploaded to the mount.
The sky was fairly clear, but not spectacularly so. The comet moves in a star rich region of the sky and is not moving very quickly anymore.
At last a clear night again! 16 x 2 minute exposures @ 1600 ISO with the ASA and 40D. Between 20:36 en 21:12 UT 0n March 2, 2009. This is the complete field of 136 x 90 arcminutes.
The sky was quite dark, 19.6 on the SQM, a magnitude brighter than usual in spite of the first quarter Moon.
4 x 2 minute exposures between 0:17 UT en 0:26UT on February 15, 2009. Modified Canon 40D @ 800 ISO. The moon was up and about 10 degrees below the comet.
The pictures were taken through the branches of some bushes because the comet was still very low.
