Black and White Sun

In this magnificent view of the full disk of the sun, we can see various active regions, sunspots and prominences. Despite still going through the solar minimum, since October the sun has notably increased its activity. Is it perhaps a sample of what awaits us for its moment of maximum activity? We will still have to wait a few years to find out.

To take this photograph I used the “Lucky imaging” technique. I made two videos of 750 frames, one to capture the disk of the sun and another for the prominences, in post process, I merged the two images and inverted them to highlight the details of the surface.
The image was taken on December 1, 2020 at 01:25 pm (UT)
I used a Coronado Solarmax II 90 solar telescope and a ZWO ASI 183MM camera.
