I just got set up and it looks great. If I go in H-Alpha from no color to
full color, much more detail in the B/W but unlike other recent days, I
can't coax out the prominences unless I drop the shutter speeds a lot. I'm
hooking up now to take some pictures at various color levels, then I'll
switch OTAs from the Lunt to a 90mm refractor white light filter and see what
happens. Thanks for the swap out idea, Tom.

As JD mentioned, there's a naked-eye sunspot that's worth a look. Here's
the white-light image of nearly the entire disc taken with a dSLR in the
focuser.

This is an animation that toggles between white light and H-alpha images
of the region around the large sunspot.
