Sun in H-Alpha and 15th of August 2021

Post by arnedanielsen »

Dear friends,

After some rain in the early morning it cleared for about an hour and half. This was just enough time to take a few close-up images in H-Alpha (including the monster prom). Unfortunately it didn't stay clear long enough to get FD images in CaK and H-Alpha.

H-Alpha image using an Explore Scientific AR152, Baader 2" 35nm H-Alpha (as ERF), Daystar Quark H-Alpha Chromosphere and ASI ZWO 174mm camera.
