Summary[edit]

Description

2013 is the year of two comets. We had PANSTARRS in the Spring, and here comes Comet ISON. This is my first view of ISON; I got up at 4:30 this morning to shoot it. The photo is a stack of three images, each a 30sec exposure at ISO 3200, taken at f/2.8 with a 180mm lens.

Only one of the three images included that streak, mostly likely a satellite, possibly an Iridium.

The emerald green comet is magnitude 8.2 (according to the ever-reliable internet); the bright star next to it is Sigma Leonis, which is magnitude 4.0. The dimmest stars in the image are about magnitude 12.

I believe there are also a few asteroids in this picture, since there are a few magnitude 12 asteroids in the scene (Doris is 12.1 and Lutetia is 12.2). An amazing picture of Lutetia was taken by the Rosetta satellite in a near fly-by: see en.wikipedia.org/wiki/21_Lutetia
