Post by arnedanielsen »

Dear friends,

Celebrated Norway's Constitution Day under the Sun and here are the resulting FD images in H-Alpha, CaK and Continuum from May 17th 2024. I also did some close-ups with the 204mm/f12 refractor, but haven't had time to process the recordings yet.

Click on images to view them in full size on AstroBin.

FD image in H-Alpha using a Coronado 60mm/BF15 w/Beloptik ITF, stopped down to 50mm, Baader 35nm H-Alpha and ASI 178mm mounted on a SkyWatcher SolarQuest.
