Comet Mc Naught above Santiago
In January 2007, after passing in the back of the Sun, comet Mc Naught reappeared in the Southern hemisphere
as one of the brightest comet of the last 50 years with a very large tail. It was visible with the naked eye even during day time.

The images below were taken 20th January 2007 from the Andes, 3500m above sea level, and show the magnificent display of the comet above Santiago de Chile. The comet tail had and extension of around 40 degrees. The very young Moon, near Santiago horizon, gives an idea of the scale of the comet tail. Camera Canon 20Da was used on a tripod (... to tell the truth ...not even a tripod ...., simply a piece of wood on a rock !). The first of the two images was chosen NASA Astronomy picture of the day..
