Interesting question, and one I guess that has lots of answers. Here are two.
1. Never point the telescope directly at the Sun and try to look through it. It can permanently damage your eye.
2. Using a telescope that is too small for the task at hand e.g. trying to use a 6" telescope to look for Pluto.
They are very useful to scientists because it helps them see stars and planets better
Telescopes are the main instruments. There are many different types, such as radio telescopes, besides the "usual" optical telescopes. Other instruments such as spectrometers are very useful too.

The non-optical telescope, primarily radio telescopes, were invented in the 1930s. One of the first and most notable radio telescopes was built by Karl Guthe Jansky in 1931.
WAS IT ERIKSON'S DISCOVERIES MADE OR BENEFITS OF THE WORLD?
radio telescopes
Telescopes that can see images of objects through radiation include radio telescopes and infrared telescopes. Radio telescopes detect radio waves emitted by celestial objects, allowing astronomers to study phenomena like pulsars and cosmic microwave background radiation. Infrared telescopes capture infrared radiation, which is useful for observing cooler objects in space, such as dust clouds and distant galaxies. Both types of telescopes provide valuable insights into the universe beyond visible light.
Researchers use all of these: -- optical telescopes -- radio telescopes -- x-ray telescopes -- infra-red telescopes -- ultraviolet telescopes

That would be "heat", except that sometimes heat can be quite useful.
There are telescopes used to detect radio waves and others to detect infrared radiation.
