WebReflecting telescopes have a few disadvantages as well. Because they are normally open, the mirrors have to be cleaned. Also, unless the mirrors and other optics are kept at the same temperature as the outside air, there will be air currents inside the telescope that will cause images to be fuzzy.

WebReflecting telescopes A telescope that uses a mirror as its primary optical element is called a reflecting telescope. Large mirrors can be made thinner and lighter than lenses of the same size, which makes reflecting scopes ideal for sending to space. (Backyard telescopes can also have mirrors, too.) WebThe reflecting telescope was developed in 1668 by Newton, though John Gregory had independently conceived of an alternative reflector design in 1663. Cassegrain introduced another variation of the reflector in 1672. …
