Constellation: Fast moving!

Fragment C, 16 April, stereo version

Fragment C, 16 April, stereo version

The stereo image was constructed by Jim Davidson from my sequence shot 16. April. His description is

"I applied a -31 degree rotation to image 1 and 17 of the sequence, then displayed 17-1, each cropped to match the background. The movement of the comet had to be horizontal to get the right effect."

Comet fragment C, still image

Below is based on the same capture as above, but processed as a still image. All 28 frames were aligned on the comet head (using K3CCDTools) and then stacked. The star trailing is due to the comets own movement against the background stars.
