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:
“The field of the poor may yield much food, but it is swept away through injustice.”
—Bible: Hebrew, Proverbs 13:23.
“Give me the splendid silent sun
with all his beams full-dazzling,
Give me juicy autumnal fruit ripe and red from the orchard,
Give me a field where the unmow’d grass grows,
Give me an arbor, give me the trellis’d grape,
Give me fresh corn and wheat, give me serene-moving animals teaching content,”
—Walt Whitman (1819–1892)
“Herein Fortune shows herself more kind
Than is her custom. It is still her use
To let the wretched man outlive his wealth,
To view with hollow eye and wrinkled brow
An age of poverty; from which lingering penance
Of such misery doth she cut me off.”
—William Shakespeare (1564–1616)
