• Never look through window glass. Glass found in household
windows is optically imperfect, and as a result, may vary
in thickness from one part of a window to the next. This
inconsistency can and will affect the ability to focus your
telescope. In most cases you will not be able to achieve a truly
sharp image, while in some cases you may actually see a
double image.
• Never look across or over objects that are producing heat
waves. This includes asphalt parking lots on hot summer days
or building rooftops.
• Hazy skies, fog and mist can also make it difficult to focus
when viewing terrestrially. The amount of detail seen under
these conditions is greatly reduced.
note: Your telescope was designed for terrestrial observation
as well as celestial observation.
