Our Moon at First Quarter

This view of the first-quarter moon displays not only the beauty of our natural satellite, but the wide field of view of the Fick Observatory CCD camera.

Our field of view is about 1/3 of a degree on a side. For comparison, the images that the Hubble Space Telescope can obtain are a mere 1/80 the area that we can see. While HST provides some spectacular images of the detailed small-scale structure of astronomical objects, wide field imaging systems such as at Fick Observatory are needed to reveal the large scale structure.

The yellow shape shows the field of view of the Hubble Space telescope on the same scale as the Fick Observatory images.
