1. Hot air is always moving through the atmosphere .This motion can cause bad images in

high power conditions, which is why it is often preferred to observe at several night .

2. Hot air on the surface of the earth will also cause waves of the air to make the image

twisted and crushed . This can make the observing conditions very bad.

3. Light pollution : try hard not to use your telescope around street lights , or under your

home’s lights.

4 .Moonlight is another factor that affects tone’s observation , as the full moon or the bright

moonlight will make the stars and the planets nearby dim .

5. Be careful not to observe from open windows (or even through closed windows)

especially during winter when the temperature outdoors varies greatly compared to the

temperature indoors.

6. Clouds in the sky can hinder your observations , but fortunately these clouds will move

often .

7. Heavy fog can make observation impossible.
