What's so interesting about observing the Sun with a Hydrogen-Alpha (Ha) filter? Well, these specialized  devices offer one of the most fantastic views in all of Astronomy.

Think about what objects change when looking through a telescope... a comet, perhaps the polar caps of Mars over time... the Sun changes by the minute!

Eruptive prominences arch out over the disk, active regions brighten and sunspots grow and widen. The Sun is a dynamic and fascinating object to watch!

Hooked yet? If not, you will be.
