Object Information                                            Imaging Details

Comet Holmes continued to expand following its eruption in late October. A tail formed in early November which disconnected around November 6. Remnants of the tail are visible in this shot.

This image is the result of a collaboration between Dave Dockery and myself. Dave took longer exposures through a slightly larger and faster telescope. I took shorter exposures to try to capture some detail in the head of the comet.

This image was acquired at ASLC's Upham dark sky site. Transparency and seeing were good.
