this week has been very bad, and today the wind has died down
and we had better, but still poor seeing (1.5/5) for the morning
solar shooting session. Today I used the two refractors for white
light and Calcium K imaing with our DMK51 camera. |
start with the full disk with the 80mm:
only one sunspot group, the close up was right on the limb at
5x - about 5 meters focal length. Seeing was not quite good enough
to show clear granulation.
now look in Calcium K light, the full disk Now back to the 80mm
with the Lunt filter B600:
bit more interesting with the plague visible. The close up with
the AR152 was a study in really bad seeing!
a lone prom on the limb - washed out because my calcium filter
has a lot of internal ghosting. But it is a nice arch!
