   Telescope eyepieces have specifications describing their lens configuration, focal length, and apparent field of view (AFOV). Field of view is an important consideration when thinking about which eyepieces you should have in your collection.

   In astronomy, the field of view (FOV) usually refers to how much of the sky we can see through the eyepiece of a telescope. If one telescope has a larger field of view than the other, it simply means I can see more of the surrounding sky with that telescope.

   The term field of view is not only used for that field itself, but also for its magnitude. In some cases, for example for telecentric lenses, it is used for the viewed area on the object plane. In some cases, the term angle of acceptance is used instead of field of view – particularly for non-imaging optical instruments.

   20 wrz 2023 · The field of view (FOV) in a telescope defines the extent of the observable universe that is visible through the eyepiece at any given moment. Knowing the FOV allows astronomers to determine the ideal eyepiece for a specific observation. There are two distinct types of FOV: the apparent field of view (AFOV) and the true field of view (TFOV).
