Excellent image of Sunspot 798

SpaceWeather.com currently has an excellent image of Sunspot 798 on their front page. You can see the image over here.

I'm kind of happy to see that the sketch I made today isn't that far off the mark.

That said, seeing the sort of detail that there is in the image mentioned above I'm very tempted to look seriously at making a Solar filter for my 'scope.
