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:
“I would say that deconstruction is affirmation rather than questioning, in a sense which is not positive: I would distinguish between the positive, or positions, and affirmations. I think that deconstruction is affirmative rather than questioning: this affirmation goes through some radical questioning, but it is not questioning in the field of analysis.”
—Jacques Derrida (b. 1930)
“It is through attentive love, the ability to ask “What are you going through?” and the ability to hear the answer that the reality of the child is both created and respected.”
—Mary Field Belenky (20th century)
“Persistence in a single view has never been regarded as a merit in political leaders.”
—Marcus Tullius Cicero (106–43 B.C.)
