This is a way cool site for historical images of the Sun with various recording methods by Greg Piepol.
SUNGAZER
Some awesome images:
A Hydrogen Alpha image - Stunning!
A Cacium K image
Wow!
A typical Sun Spot [857]
This prominence was extremly hard to image. Larger prominences seem to stand out against the overwhelmingly brighter disk but the thin, tenuous ones really push the limits of the control software and your processing skills. It was a very rewarding capture! [Greg]
I love the passion Greg has for the science of the Sun!
