FOV (deg) = (Sensor Width in mm / Telescope Focal Length in mm) x 57.3

Enter your telescope focal length and focal ratio. Add any focal modifiers. astro fov calculator 2021

While the year is now past 2021, the fundamental mathematics of Field of View (FOV) do not change. However, the "2021 era" marked a specific transition in how Astrophotography FOV is calculated—moving away from standalone apps to powerful, free web-based engines. FOV (deg) = (Sensor Width in mm /

The FOV is determined by your camera's sensor size and the telescope's focal length: However, the "2021 era" marked a specific transition

Helps you determine if your camera pixel size matches your telescope's focal length (avoiding undersampling or oversampling).

True FOV = (46 / 1200) x 57.3 = 2.2 Degrees
