Field of View Comparison
One of the "trick" features of video astronomy
is the apparent high magnification. This is due in part to the
small surface area of the imaging device, typically 1/3"
to 1/2". The image below shows the "field of view"
of my Astrovid 2000 camera as compared to a 9mm Nagler eyepiece
in two different telescopes.
