So you want to figure out how to use your telescope with eyepieces and camera for a particular astronomical object. Some are big like the moon, some are big but very faint. Others are small like planets and stars. I want to demonstrate the use of two nice field-of-view FOV calculators for online use. The use of both is very similar but the results are presented differently. All involve specifying the object and telescope’s focal length and aperture. Also the mode of use whether eyepiece (FL) or camera type needs to be selected. The first shown here is this one from Sky at Night magazine. This calculator shows the realistic size of the magnified object.

The second calculator from the Astronomy Tools website overlays the
various choices to show the effect of different telescopes and eyepieces
or cameras all on one picture.
