Sunspot AR2546 – May 22, 2016
Looking at the following image I can only think: “We live on a really small planet…”.
The shot was acquired using a filtered 8 inch homemade Newtonian and ASI 174MM camera with a Ha (30nm bandwidth) filter (for contrast), under poor seeing conditions. 500frames were stacked out of 7000. Note the circle showing the size of Earth for comparison.
