when light enters a telescope it can "hit" the side and refract and cause "blurryness"
on the digital image collector element
this scattered light can obscure objects of low light density or objects that require a sharp releif
to determin composition
this is optical news using a carbon nano tube to "absorbe" rather than "reflect" light so the image is sharper and more clearly imaged
interesting post, thanks for the information. More than likely the purpose is to get a better quality image as you say given the darker material being
used. Fascinating how humans can create and than grow on our past inventions
