Field of View Calculator
To bring up a field of view, select the telescope with the left-hand drop-down menu, then select the eyepiece or camera with the right-hand drop-down menu. Then click on 'Objects menu' to choose the object you wish to view. Finally, hit submit to generate the view. If your equipment is not in the lists, you can enter its details in the relevant text boxes.
