Focal Length millimeters
Width pixels
Height pixels

Image Scale arcsecs per pixel
FOV Width arcmins
FOV Height arcmins

This calculator may be used to calculate the image scale for a camera/scope combination. The total field of view of the camera is then derived using this image scale.

Pixel Size: Enter the pixel size of the camera in microns.
Focal length: Enter the optical focal length in millimeters.
Width: Enter the width of the camera in pixels.
Height: Enter the height of the camera in pixels.
Calculate: When you have entered and converted all your inputs to the proper units, click "Calculate." The Image Scale and the Field of View Width and Height will be calculated in the fields below.
