Telescopes & instruments · FOV = 3437.75 × sensor(mm) / focal(mm)
Field of View
The angular extent of sky a camera frames, from the sensor size and focal length. A shorter focal length or a larger sensor takes in more sky.
Field of view80.787arcmin
Formula: FOV = 3437.75 × sensor(mm) / focal(mm)
Worked example
With the default inputs, field of view evaluates to 80.787 arcmin — 23.5 mm at 1000 mm → ~81′. The validator recomputes this against the known value on every build, so the formula is checked, not asserted.
