Here are a few images of the Solar Photosphere, the outer layer of the Sun.
For most of my WL images I use a 6" f8 achromatic refractor with a Baader WL filter plus usually a couple other colored filters that help cut through atmospheric turbulence.
The camera is a pure monochromatic high speed video camera which captures frames at about 60 per second. Each capture is usually 1 minute for about 3600 frames which are then processed into a single image.
Close ups with good conditions show a granular surface. These granules are ~1000 km across and have a life of about 10 to 20 minutes.
