A Last Look at Comet Holmes

  • On November 4th, Comet 17P/Holmes was about 2nd magnitude and spanned approximately 20 arc-minutes on the sky, about 2/3 the size of the Full Moon. Separate 20-second exposures through r, i and z filters were combined to make this monster 16-megapixel full-color view. The Megacam instrument at the MMT Observatory was used for this image.
