Image Data

Designation C/2000-06
Object type Comet
Description An animation of an unspectacular comet discovered by the SOHO orbiting solar observatory.  At around mag 6 it was located between Gemini and Orion low in the predawn sky at only 0.26 astronomical units from earth.

The image was stretched to a bright grey background on purpose in order to show the hint of a tail. In frame 44 a satellite crossed the field of view and - of course - the comet.

Exposure L  60 x 20 s @ -18C, 2x2 binned, unguided.

The 60 individual images were already being recorded when I discovered that the comet was incorrectly framed and moving the opposite way on the chip (away from center)

Optics Astro-Physics AP155EDFS @ f/7.2 (prime focus)
