In late October, 2007, Comet Holmes suddenly flared in brightness from magnitude 18 to magnitude 3 (most visible stars are dimmer than magnitude 3). It's not known for certain why this is, or how long the effect will last. Although the popular press has pretty much ignored this, the amateur astronomy community has been fascinated by it and the astronomy discussion boards are filled with both visual sighting reports and images of the comet. This was captured 10-28-2007 at Urban Observatory, using an ST-10XEI camera and a TMB130SS APO refractor. 10 luminance images of 60 seconds each were combines with 6 30 second exposures each of red, green, and blue. |
