Clouds and comet and dome

This image was taken on Wednesday morning and shows comet Holmes which has continued to stay bright while it expands - if you could condense all the light from the comet back into a point, it would still be one of the brightest objects in this section of sky. The comet is just left of center. The Spacewatch 36 inch dome is in the foreground with a bank of clouds that are slowly moving into the area. This image was taken with my 24mm f/1.8 lens with an exposure of 30 seconds at ISO 400.
