Field of View
Kepler has a fixed field of view (FOV) against the sky. The diagram to the right shows the celestial coordinates and where the detector fields are located, along with the locations of a few bright stars with celestial north at the top left corner. The mission website has a calculator that will determine if a given object falls in the FOV, and if so, where it will appear in the photo detector output data stream. Data on extrasolar planet candidates is submitted to the Kepler Follow-up Program, or KFOP, to conduct follow-up observations.
- Kepler’s field of view covers 115 square degrees, around 0.28 percent of the sky, or “about two scoops of the Big Dipper.” It means that it would take around 400 Kepler like telescopes to cover whole sky.

Famous quotes containing the words field of, field and/or view:
“... many American Jews have a morbid tendency to exaggerate their handicaps and difficulties. ... There is no doubt that the Jew ... has to be twice as good as the average non- Jew to succeed in many a field of endeavor. But to dwell upon these injustices to the point of self-pity is to weaken the personality unnecessarily. Every human being has handicaps of one sort or another. The brave individual accepts them and by accepting conquers them.”
—Agnes E. Meyer (1887–1970)
“Whether in the field of health, education or welfare, I have put my emphasis on preventive rather than curative programs and tried to influence our elaborate, costly and ill- co-ordinated welfare organizations in that direction. Unfortunately the momentum of social work is still directed toward compensating the victims of our society for its injustices rather than eliminating those injustices.”
—Agnes E. Meyer (1887–1970)
“Where has it gone, the lifetime?
Search me. What’s left is drear.
Unchilded and unwifed, I’m
Able to view that clear:
So final. And so near.”
—Philip Larkin (1922–1986)
