This photo of comet 17P / Holmes was taken by Randy Buchwald and Scott Berg on Monday, October 29, 2007 at about 9pm CST from the Harken Observatory. The imager was the Stellacam attached to an f/6.3 reducer, allowing the entire comet to be in one field. The video output was captured to a digital videorecorder. Randy then combined about 1500 frames using the Registax software.
Once you know where and what to look for, the comet is visible naked eye as a dim point near Perseus.
