Solar Activity Today

I was curious how longer focal length changed the image resolution. So I tested with BORG 89ED (600mm f.l.) today. It was 400mm last time.

Unfortunately hazy sky and passing clouds were not good as test today. My movie is often interrupted. Meanwhile this was good proof how Hinode SG was switching off and on automatically, depending on the clouds. Anyway, as expected, it keeps tracking to the end.


About 6 hours time sequence. 4-shot stacked in each frame

I will make one more test under the better sky condition.
