Select a celestial object (e.g., M31, M42) to see how it fits in the field.

In astrophotography, FOV is essential for:

Field of view (FOV) refers to the angular diameter of the sky that an instrument, such as a telescope or camera, can observe or capture. In astronomy and astrophotography, FOV is a critical parameter, as it determines the extent of the sky that can be observed or recorded. A wider FOV allows for the observation of larger areas of the sky, while a narrower FOV provides higher magnification and more detailed views of smaller regions. Sensor size databases

If your camera lacks active cooling (like a stock DSLR), CCDCalc will tell you your maximum exposure before “hot” noise ruins your sub-frame.
