Image Gallery - The Sun

The Sun is a difficult imaging target, not only because it is so bright, but also because the air is usually quite turbulent in the daytime. When viewed in white light, few features are visible except for sunspots, cool active areas on the surface. The Sun can also be viewed through a filter that passes only the red light of hot hydrogen. When seen this way, great filamentary detail is seen on the surface, and prominences rise around the limbs.

NOAA 9393
Sunspot group NOAA 9393, UT 2001.03.28 23:46. Imaged with a Nikon Coolpix 990 digital camera attached to a 500mm f/5.6 Maksutov telescope + 12.4mm eyepiece. This sunspot group has a surface area equal to about 14 Earths. The next day this region produced a large coronal mass ejection, resulting in a spectacular auroral display on the evening of March 31.
