The corrector plates on Maksutov and Schmidt-Cassegrain optics are located in an exposed position at the front end of the tube. Even low levels of humidity lead to fogging of the optics with dew.

Refractors are usually already supplied with a dew shield and in Newtonian telescopes the entire tube acts as a dew shield. For SC and Maksutov telescopes, on the other hand, a dew shield is a very useful accessory.
