Grains in the Chromosphere

Here we see 2 movies made from the light of the Calcium K line. It shows the middle levels of the chromospheres, and chromospheric grains, or bright points, are easily seen as small grainy flashes. Both movies were captured at 1 minute intervals using a Lunt CaK Diagonal on the Tak 102. The 31AU03 was used for a Hi Res wide view.
