AR1476 is a prominent sunspot group that looks great in white light and through 
a Hydrogen alpha filter.  I used two different telescopes to make a movie that 
shows both views of this region.  The 70mm Pronto has become a dedicated solar 
scope with a Coronado 60mm SolarMax in front of the objective.  The TV101 uses 
a Lunt solar wedge to provide white-light views.  I imaged the region in 
H-alpha at 11:08 this morning, and changed out scopes to image it in white 
light 18 minutes later.  The resulting animated GIF might take a little while 
to load.


It's interesting to see how some of the fainter photosphere details such as 
sunspot penumbras are wiped out by the chromosphere, and how filaments 
disappear in the white-light view.
