Cycle 25 Plage and Filaments - 30th August

Cycle 25 is certainly starting to get underway on our star.  While the magnetic fields may not be strong enough to form sunspots in this image, the are signs of turbulence in the form of both brighter page and also the darker patches of filaments - cooler clouds of plasma held aloft by magnetic fields.  This image was taken with the Coronado SM90 double stacked with a Daystar Quark and Airylab 2.8x telecentric and a PGR Grasshopper 3 camera with IMX174 chip.
