GENERAL OBSERVING HINTS

When using any optical instrument, there are a few things to remember to ensure you get the best possible image .
• 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 . Knowing how to use it for this purpose has been described
already as it is quite simple and straightforward . Your telescope can also be used for casual astronomical observing
which will be discussed in the next sections .
