The Sun Solar System: the Moon Planets observing logs

March 30th, 2004: Lunar observing log: Overview of a 9-day-old-moon

The image below was taken on March 30th 2004 at 18:57 UT. The Moon was 9.1 days old and about 67% of the surface was illuminated by the Sun. The instrument used was an f 4.7 10-inch Synta Skywatcher Newtonian on an equatorial mount (Lichtenknecker). I shot the image with a Nikon Coolpix 4500 mounted to the telescope with a Vixen digital camera adaptor. The eyepiece used was a 25mm Vixen Lanthanum (48x). The camera's settings were: exposure time 1/60s, f 3.0, ISO 100, and no optical or digital zoom. The final image below is the result of 15 single images (2272x1704) stacked with Keith's Image Stacker (Mac). The stacked image was resized and the orientation was changed (the same is in the Rukl) using image-processing software. I also applied some unsharp masking. I did not use any filters.

Some striking features on the (9.1-day-old) Moon

In the North we see Plato, the big crater just south of Mare Frigoris (Rukl 3). South of Plato, in Mare Imbrium, several mountains can be detected, Mons Pico and Montes Teneriffe among them (Rukl 11). Across Mare Imbrium, on the southern edge, just behind the Montes Carpatus, lies another big crater near the terminator, Copernicus (Rukl 31). If you go further to the south from Copernicus to the next crater visible on the terminator (Bullialdus), you will be crossing three Mares, Mare Insulanum (Rukl 31/42), Mare Cognitum (Rukl 42) and finally Mare Nubium (Rukl 53/54). In Mare Nubium, near the terminator the outline of Bullialdus is visible, with Bullialdus A and B just to the south of the crater rim.

The Lunar surface south of Mare Nubium is heavily cratered. Near the terminator, from North to South, we see Wilhelm, Montanari and Longomontanus (Rukl 64/72). To the west of Wilhelm lies Tycho with its central peak clearly visible. A bit further south from Longomontanus lies Clavius (Rukl 72) with its cratered floor. To the southwest of Clavius the outline of Blancanus is visible. To the southeast (Rukl 73) you can see Gruemberger, Moretus, Short and the outline of Newton.
