These objects were discovered in the 18th century and were catalogued so that eyeball observers using small telescopes would not confuse them with comets. With the naked eye as a detector, most of these objects appear as dim grayish blobs. They are considered a challenge to find for many amateur astronomers. These objects are generally of large angular size and hence larger than the typical field of view of many CCD detector systems; hence CCD images of these objects are somewhat rare compared to photographic ones. In this resource, we offer CCD images of many of these objects, taken with a variety of different telescopes, along with a description or narration of brief facts about them. Where appropriate we have linked additional images or diagrams to further explain their properties or structure.
