Sun FD in H-Alpha and CaK 10th of November 2021

Post by arnedanielsen »

Dear friends,

It's been 10 days since my last solar imaging session (due to weather and other obligation), but today I was able to take a few shots. The solar altitude was only 8 degrees and the seeing poor, but that's how it is my latitude this time of the year.

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.
