Solstice Sunspots

 Today is the Winter Solstice and the shortest day of the year in the Northern Hemisphere .  There are currently many sunspots and active regions on the sun:



These images were taken with an AT72EDII refractor, Lunt solar wedge + ND-0.9 filter, and E-M5iii camera, ISO 200, 1/800 s.  These are both the same image - the second one has false color added. Sometimes this results in a more interesting picture.

Nothing to worry about when photographing the moon (other than dropping things in the dark). Here is the 9.9d-old Solstice moon:


E-M5iii + AT72EDII.  ISO 200, 1/800 s.
