Sun FD in H-Alpha and CaK 28th of August 2021

Post by arnedanielsen »

Dear friends,

The seeing was not very good today and by the time the Sun was accessible from my observatory some clouds started to interfere. But I managed to get a couple of FD images in both H-Alpha and CaK.

FD image in H-Alpha using a Takahashi Sky-90II with Coronado 90mm/BF15, Coronado 2x CeMax and ASI 1600mm PRO.
