This image shows the comet C/2012 K5 (LINEAR) on the evening of December 30th 2012. It is a composite of 5 RGB sets of 1 min. exposition each for the stars and 5 LRGB sets tracked on the comet (see the bottom image) using the comet tracking capability of my DDM 85 mount. The processing was tricky due to the very fast comet’s motion (about 10 arcsec per minute).
