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.
Sun FD in H-Alpha 28th of August 2021
FD image in CaK using a William Optics ZenithStar 61II stopped down to 46mm, Lunt CaK 1200 module, Coronado 2x CeMax and ASI 183mm camera.
Sun FD in CaK 28th of August 2021
Sun FD in CaK 28th of August 2021 - colorized
As usual click on links to view full size images.
Thanks and best regards,
Arne
