 This is another attempt to capture the full disk of the sun with the PST. The afocal method was used with my Sony P10 set for 3x optical zoom. The prominences were from the rather overexposed red channel, and the disk was with the green channel. Internal scattering within the zoom lens causes the glow around the disk in this composite.
