With Lunt LS100THa
For Sunday, October 20, 2013
Images below are 1290 wide and non clickable
the sun had an extraordinary amount of filaments on the disk
- proms seen in silhouette against the sun. The sunspots or as
we call them in Halpha imaging - Active regions were plentiful
and some had some small flaring action. The Proms along the limb
were faint, but had some interesting details as we zoomed in. |

disk image - Lunt LS100 with .5x Antares focal reducer:
we zoom into the individual regions with the 3x Klee Barlow,
resulting in a 6x increase over the above image.
we increase the exposure and lower and gamma to see the prominences
on the limb.
we go off band about 3/4 Angstroms into the "Red wing of
Halpha" to see the white micro flares around the sunspots
known as "Ellerman bombs"
