Apollo 11: [NE/J12] The best time to see the Apollo 11 landing site is around Day 5, or 4-5 days after full Moon. You will find the landing site just east of the crater Sabine. In the close-by neighborhood are three tiny craters named for the astronauts of Apollo 11: Aldrin, Collins, and Armstrong. These craters can be used to test your telescope optics and the seeing conditions. From west to east, the crater diameters are: Aldrin (2.1 miles), Collins (1.5 miles) and Armstrong (2.9 miles).
OF ADDITIONAL INTEREST: MARS, THE MOON AND VENUS:
On Monday evening, Mars, the Moon, and Venus will be lined up just over the SW horizon. The Moon will be just 3° from Mars and 8° from Venus, which will be a very bright -4.4 Mag (this should be bright enough to see in daylight if you know exactly where to look). To locate Venus in the daytime, use a home-made quadrant (for measuring altitude) and a compass. To make such a quadrant, attach a protractor to a rectangular stick (like a wooden ruler). Put a screw through the zero point of the protractor, tie a string to the screw and attach a weight to the string. Find out the current azimuth and altitude of Venus by using an app like Sky Safari. Using your quadrant and a compass, scan the approximate area with your binoculars. With practice you’ll be able to point exactly to the object in question.
It is highly recommended that you get a copy of Sky and Telescope’s Field Map of the Moon, the very finest Moon map available for use at the telescope. It is available for $10.95 at www.skyandtelescope.com and on Amazon. All features mentioned in this blog will be keyed to the grid on the Field Map and will look like this: Plato: [NW/D9]
