Comet 177P is moving at a relative speed of 3.6 arc seconds per minute against the star field in Hercules. This makes it difficult to image as one must take short exposures so the comet is not blurred – and autoguiding on a comet is very difficult.
But the good news is that the fast-moving comets make for nice movies. I’ve put a short, modem-friendly 432 kb movie that shows seven arc minutes of travel from 59 minutes of subframes.
