H-alpha Sun – August 27, 2016

Good activity these days on the Sun, despite lacking any great sunspot group or large prominence.

The following shots and animations were acquired under good seeing conditions on an imaging  session together with my wife not far from home.

The equipment: TS 115mm F/7 APO Refractor, Quark chromosphere H-alpha filter, Baader UV/IR cut filter, ASI 174MM camera.

First, a wide two-panel view showing the Sun’s western limb with a lot of activity:

And a more detailed view of some of the prominences:

Active region 2581 with some interesting detail:

And two animations (a third much longer one is being processed) :

-the first one shows the prominences dancing over a 20 minute period:
