Terrestrial objects must be at least fifty feet away to be
viewed clearly. You may view objects in the daytime sky such
as aircraft and birds, but be careful never to view the sun
with your ExploraScope or any other telescope without using
the proper filtering equipment.
When working with any optical instrument, there are a few
things to remember to ensure you get the best possible image.
If you wear corrective lenses (specifically glasses), you may
want to remove them when observing with an eyepiece
attached to the telescope. If you have astigmatism, corrective
lenses must be worn at all times.
Hazy skies, fog, and mist can make it difficult to focus
1
when viewing terrestrially. The amount of detail seen
under these conditions is greatly reduced.
Never look across or over objects that are producing heat
2
waves. This includes cars and asphalt parking lots on hot
summer days or building rooftops. Heat waves will
distort the atmosphere and affect your view in many of
the same ways as uneven window glass.
Never look through window glass. Glass found in
3
household windows is optically imperfect. This
inconsistency can and will distort images and affect your
ability to focus the telescope. In most cases you will not
be able to achieve a truly sharp image, while in some
cases you may actually see double.
