Just read a thread on discussion group

Here are 4 images of AR11041 with the filter tuned progressively into the blue wing. Changes in a small, active filament (arrowed) can be seen in the 3 minute progression into the blue wing. Changes in brightness of plages can also be seen.

Though the LS50 be little, it be mighty....IMHO.
