Description

An image taken in white light with the Herschel prism. The sunspot groups 2993 and 2994 have appeared. Well visible are the umbras and penumbras as well as some light bridges in the umbras.

For this image I took 5000 photos and stacked only the best 10 because of the horrible seeing. Because the sun is so bright, the signal-to-noise ratio is still quite good.
