Coverage of
common CCDs on various targets as a function of focal
length
Just what will you actually be able to fit on that scope
and camera? You might be surprised. Many CCD cameras have
fairly small chips that make their view of the universe
about as big as a 6 mm Plossl gives you. Click on the links
below to see examples of approximate coverage of different
sized CCDs as a function of scope focal length. Images
taken from the Digitized Sky Survey.
Type 1/3" CCDs (~6 mm diagonal)
