Sol

The Sun Saturday. You can just make out the sun spot AR1791 centre left. They are caused by interactions with the Sun's magnetic field, But a sunspot is somewhat like the cap on a coke bottle: shake it up, and you can generate a big eruption. Sunspots occur over regions of intense magnetic activity, and when that energy is released, solar flares and big storms called coronal mass ejections erupt from sunspots. I may invest in a solar continuum filter. Those using them appear to show granulation in the surface. I would be grateful for a bit of feedback if you use one. This image was taken through a avi video file from my DSLR through the 90mm refractor Approx 1000 frames stacked in Registax and colour corrected from a white light filter.
