How do you calculate field of view astrophotography?
The standard quick calculation formula for arcsec/pixel is 206.265*pixel size (um) / focal length (mm).
This yields a value of 0.589+ for your camera, scope and focal reducer.
Multiply this by the number of pixels in the sensor and you get the FOV of the entire sensor..
How do you find the field of view for astrophotography?
In astronomy, the field of view is the amount of sky you can see, whether with your unaided vision, binoculars, or a telescope.
Field of view is measured as an angle, in degrees (◦), minutes ( ), and seconds ( ) of arc (1◦ = 60 = 3600 ).
If you had eyes on all sides of your head, you would have a 360◦ field of view..
How do you find the field of view of an eyepiece?
Determine Your True Field of View
1Divide the focal length of the scope, 1,200mm, by the focal length of the eyepiece, 25mm, to determine that that combination provides 48X magnification.
2) Divide the AFoV, 50\xc2\xb0, by the magnification, 48X, to yield a TFoV of 50/48, or about 1.0417\xc2\xb0..How do you find the field of view of an eyepiece?
The apparent FOV for each eyepiece ranges from 45o to 68o and is a result of how the eyepiece is designed.
When used in this example with an 8-inch telescope with a focal length of 2032 millimeters, the magnifications range from 41x to 75x.
The resulting telescope FOV is then just FOV = Eyepiece FOV/magnification..

What determines a telescopes field of view?
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 quantifies the amount of sky visible in a particular scope with a particular eyepiece..
What is field of view in astronomy?

What is the field of view in astronomy?
When used in this example with an 8-inch telescope with a focal length of 2032 millimeters, the magnifications range from 41x to 75x.
The resulting telescope FOV is then just FOV = Eyepiece FOV/magnification.
For the Optilix 2” eyepiece, the FOV is then 60o/51 = 1.18o..
What is the field of view of the telescope eyepieces?
The field of view is the circle of sky visible through the eyepiece.
Generally speaking, as you exchange eyepieces to get a higher magnification, the field of view is a smaller piece of the sky.
We measure FOV in degrees or fractions of a degree..
- Take the two and use this formula: (135.3x D) / L.
This will give you the field of view (in arcminutes) for your telescope and imaging device.
Where D is the size of the Chip, L is the focal length of your telescope.
Therefore, using a Nightscape 8300 with an 11-inch EdgeHD yields a field of view of 21.62 arc minutes. - The field of view is the circle of sky visible through the eyepiece.
