Details:
The image was taken on the converted solar unigraph (Schaer system) at the new location 5m above the ground.
It is one of the first pictures taken with an original focal length (approximately 10 meters).
Although the etalone had been set to the center of Halpha, the photosphheric edge of the sun (arrows) can still be seen in the region around the sun's north pole.
At the aquator, on the other hand, the chromosphere is dense!
It may be that coronal holes are also visible in the H-alpha chromosphere? For this purpose, two SDO recordings were copied at a similar time.
