Actually the picture probably looks like this because all that is photographed was the inner corona and through a 10" telescope at prime focus the field of view
would be only about a 1.25 degree of sky at the most, and probably a little less. Don't need a 10" telescope to take a picture of an Eclipse of the Sun
just a pretty good length telephoto lens on the camera like perhaps 300 to 600mm telephoto lens (the 10" telescope was like a 1500mm lens). Fiddling around though trying to get a
light meter reading and taking a photo during a 2 minutes 56 second Eclipse - well time moves quickly. I just wanted to show the Shadow Bands from the Sun starting to peek around
the surface of the Moon and it was just a sliver of Sun if that, being that light bends due to gravity and with an Eclipse in 1921, they proved Einstein's Theory of Relativity
that light would be bent by gravitational pull and the stars are not where you quite see them, but a little displaced by light being bended by gravity. The telescope shows
that all the time by the star not quite being where you see it with the naked eye or a finder, with more magnification showing the small displacement.
Unless you have lots of money and can chase Eclipses everywhere, a person can still get ready by learning more about it if an Eclipse comes nearer to you.
