Halos and domes
The two Spacewatch telescope domes are shown against a sky with the Moon and its halo. The 1.8-m telescope dome is on the left and the 36 inch Mosaic camera dome is just right of the Moon. This image was taken with my 10mm fisheye lens with an exposure of 30 seconds at f/2.8, ISO 400.
