I have a TeleVue Pronto set up to quickly switch from an H-alpha to a Herschel wedge view. Here is a toggle animation between two images made at 17:17 UT on December 28. The frames are registered on the prominent sunspot, and there was some rotation of the disc in the 4 1/2 minutes during the filter change-out.

That is neat... looked at it for a few minutes. It is cool to see how all the prominences line up with surface features from white light to Ha light.
