6.5.23: AR3297 /96, harvest of today in CaK & Ha

Post by Dennis »

Hi,
I managed to do a little comparison in both wavelengths, until the seeing was "drained".
Finally i came back to a bit of h-alpha imaging and it feels like coming home after a long trip in 393nm.
Now off to enjoy the good weather.

Nice weekend to all.


Calcium K:
30/1891 best images, 6.8ms exposures (126 fps)

H-alpha:
50/1636 best images, 9.1ms exposures (109 fps)

Perfect detailed pictures. CaK is superb.


I do not look at the sky with the eyes of an astronomer, but of a person looking for the beauty of nature.
