For BP and RP, it is the observation time of the BP CCD transit. the field of view is as it sounds its literally the amount of sky that is viewed field of view through any given scope is also determined by the eyepiece and the resulting magnification The are newer eyepieces are have been designed that will give a much larger FOV compared to a normal eyepiece of the same size. View 80 degrees 60 degrees 30 degrees 15 degrees Variable. Many of these programs allow you to overlay an eyepiece or camera field of view on the displayed portion of the sky. CCD FOV calculator. These CCD's share an Analog to Digital converter, and other readout electronics. The chart below also shows the distance you can view small objects from such as car number plates with varying lens sizes. The Field of View (FOV) The field-of-view (FOV) is the range of angles from which the incident radiation can be collected by the detector. The Field of View Calculator (or FOV) is used to help predetermine proper lens selection prior to installation. Exposure time, 1 s. Piart for mechanical conception and realization and to F.
