Telescopes open our eyes to the marvel of the cosmos: the telescope field of view calculator will tell you exactly how much! Here you will learn: The basics of telescopes and eyepieces; What are the mysterious numbers on an eyepiece?; What is the field of view of a telescope?; and How...
To bring up a field of view, select your telescope make and model, then select your camera make and model. You can select your eyepiece or binoculars by clicking 'Mode'. Click on 'Targets' to choose the object you wish to view.
This calculator tool computes the Field of View seen by your camera and lens. Field of View is an angle which depends on the focal length and sensor size, but the calculator also computes dimensional Field of View sizes (width, height, or diagonal fields) at some specific distance, like at...
Calculator Tool: Field of View of a Camera Sensor width: Focal length: Field of view: calc Enter input values with units, where appropriate. After you have modified some inputs, click the “calc” button to recalculate the output. The field of view gets particularly small when using a...
Another simple formula will result in a more accurate determination of true field. The actual apparent field need not be known: TF = EPFS/TFL x 57.296 where EPFS = eyepiece field stop, TFL = telescope focal length Example of a difference in the formulae: ...
Astronomy Tools Field of View Calculatoris the best tool I know of for visualizing the field of view of any scope and camera combination. If your scope or camera are not already on the list you can create them as custom. Use the images of DSOs and planets to get scale not for what de...
The present invention relates generally to a reflex-type sight and particularly to a sight for use in a bow having a wide field of view and touch-button adjustment for range. BACKGROUND OF THE INVENTION Reflex-type sights are generally used with guns and primarily use telescope-like type tube...
Calculating the field of view is a little more complicated because a number of variables can alter the equation. Thankfully, you can get around this (and the angle of view equation) easily by using an online field-of-view calculator, like this one from Omni Calculator. Field of view = 2...
