Happy Valentine's Day!

What kind of camera/telescope/whatever was used to take that picture, Dr. T?

I'm guessing that it's a hydrogen-alpha image; but if it's from something like Solar Dynamics Observatory, they have lots of wavelengths available! SDO is 2 years old this week, by the way.

White light images tend to look like this (much less resolution, of course).


Thanks, Barb. That is a treat!
