Knowing the field of view of a CCD camera on a certain telescope is critical when selecting targets for imaging.  It is also a useful way of comparing cameras or combinations of cameras and telescopes.  Pixel size factors into the resolution obtainable with a given setup and is one way to match an appropriate CCD and scope.  For more details, visit the Understanding Image Scale and Field of View page.

The camera and telescopes listed below are those for which data was readily available.  There are currently 76 cameras and 140 telescopes to choose from.  For other setups, data can be entered manually.

Select a CCD camera and telescope from the menus below.  The pixel resolution and field of view will be displayed below.  You may also change the binning to see the effect this has on pixel resolution.
