TERRESTRIAL AND ASTRONOMICAL VIEWING
Your Zhumell binoculars are equipped for both large-magnification
terrestrial viewing and astronomical viewing purposes. Although
they are light enough to hold in your hand, we recommend
these binoculars be mounted to a tripod for best results. At high
magnification, even the smallest movement of the binoculars results in
a large jolt to the view.
To use your binoculars for land-based viewing, mount to a tripod and
point the binoculars at the object you’d like to see. Adjust the focus
knobs to bring the object into clear view.
To use your binoculars for astronomical viewing, read the following
guide to achieve viewing success.
SELECTING A VIEWING SITE
The ideal site for using your binoculars for astronomical viewing is in the
middle of nowhere. Most users don’t have access to the darkest of skies,
however, so select a site that is both far from light pollution and practical
for travel. Avoid street lights, yard lighting, rooftops, and chimneys, and
never observe through an open window indoors. Be sure your site is out-
of-town or very dark and has clear view of a large portion of the sky.
SEEING AND TRANSPARENCY
Atmospheric conditions are of the utmost importance when considering
viewing conditions for your astronomical binoculars. These conditions are
commonly referred to as “seeing.” When seeing is good, star twinkling
is minimal and objects appear steady in your lenses. Seeing is best
overhead, worst at the horizon, and generally better after midnight. You
can’t see the stars without looking through the atmosphere, so the
clearer the air and the higher your altitude, the better seeing conditions
you will encounter.
