ASTRONOMICAL OBSERVATION TIPS

Remember, your binoculars achieve a high level of magnification, 
which shrinks your field of view accordingly. Objects will appear 
to move faster at high magnification, and frequent positional 
adjustments will need to be made.

THE MOON

The Earth’s moon is one of the easiest and most rewarding targets 
at which to point your binoculars. Its rocky, cratered surface is close 
enough to be rendered in some detail, and allows for satisfying 
exploration.  The best time for lunar viewing is during its partial 
phases, when shadows fall on the craters and canyon walls to give 
them definition. Even though the full moon may look like a  
tempting target, the light is too bright and the definition too low for 
optimal viewing.

THE PLANETS

The planets are beautiful and popular targets for astronomers, but 
they can be more difficult to keep track of than the stars or moon. 
Planetary position charts can readily be found online or in any 
astronomical publication. Sun and Moon aside, the brightest objects 
in the night sky are Venus, Mars, Jupiter, and Saturn. The apparent 
size of planets can be quite small, but high-power binoculars provide 
an adequately enjoyable view.
