The field of view of a telescope or a photo camera, for example, is usually understood as the range of angular directions in which objects can be observed for a fixed orientation of the instrument. (One may of course observe a wider range by combining images from different instrument ...
A drift test lets you figure out just how much of the sky you can keep in your sights.Any combination of telescope and eyepiece has a specific true field of view (TFoV), which is determined solely by the focal length of the telescope and the field stop diameter of the eyepiece. TFoV...

We have known the condition independent of frequency in case of a single Gaussian beam on an optical axis, but have not known one in case of a beam propagated off the axis or tilted beam, which appears in a wide field-of-view telescope. We first show relations between an arbit...
so the formula reduces to or where theta is the angular field of view. This formula lets you figure out the angle of view of the camera. Let’s take an example :What is your working distance to get an 10″ field of view with a 50mm lens on a linescan camera with array length 0.6...
No, the field stop is the edge of the field of view, sometimes it is well defined and sharp, sometimes it is sorta fuzzy. #3 TOMDEY James Webb Space Telescope Posts:17,139 Joined:10 Feb 2014 Loc:Springwater, NY Posted15 July 2023 - 04:32 AM ...

where EPFS = eyepiece field stop, TFL = telescope focal length Example of a difference in the formulae: 31mm Nagler in my scope: The TF = AF/M formula gives a true field of 1.392° The TF = EPFS/TFL x 57.296 formula gives a true field of 1.318°, 5.3% smaller. ...
An optical assembly for a point action camera or other compact digital camera having a wide field of view, includes multiple lens elements, including at least one lens element that
