Sunspot group 798

Wow, this sunspot group is huge! As Macclesfield Astronomical Society's solar telescope is sat under my desk at the moment I thought I would have a look. This image was made by holding my little digital camera to the eyepiece of the telescope so it isn't as well focused as it could be, but it's not bad. There is a large prominance on the edge of the Sun on the right hand side of the image. To give you some idea of the scale, Earth would be dwarfed if you put it next to the prominance.
