Capturing the full disc of the Sun.
Andy Devey
This month I thought that I should cover how to capture the Sun’s full disc. The
Sun is a very large target and beyond the size of most CCD chips in the video
cameras that are now available to the amateur astronomer. Some of my friends
use the larger chips in their SLR’s to capture the full disc through a telescope but
these cameras have colour CCD chips and this will wash out much of the detail that
is available to the monochrome CCD chip. The options available to today’s amateur
solar astronomer are dependent on the personal goals that individuals set in this
field.
Some of my friends have opted for large frame CCD cameras such as the new
