If the photosphere of the Sun is the region producing visible light, then why is it
so difficult to obtain an image of this light from space? There are no images that I
can find that have been taken by anything resembling a normal camera, with a solar
This is an image of the photosphere, from the SDO, but the 'camera' is a little more
complex than I would have thought necessary.
Perhaps someone can explain to me why a Michelson Interferometer is the device
required to 'see' visible light, from space?
