The Moon at 26 Days Old


0.25 seconds exposure, Agfa HDC 400 film.
5" f/5 refractor at prime focus.

The rising of the waning cresent moon signals the end of a long night of successful observing. This photograph was actually the last I made on an observing trip before moving from Western Australia to the USA. The very bright object to the left of the Moon is the planet Saturn, while just above the Moon is the star epsilon tauri.


0.05 seconds exposure, Meade 416XTE CCD.
300mm f/6 newtonian at prime focus.

The large walled plain is Grimaldi while just below it the crater Helevius shows promiently. Towards the bottom of the image are the craters Cardanus and Krafft.

When the Moon is this thin, not many sunlit features are visible. However much of the surface that is not in sunlight is observable because of the bright earthshine.

A longer exposure shows the region around Mare Humorum illuminated by the nearly full Earth.
