Sunspot AR2546 – May 20, 2016

Good seeing (but far from perfect) allowed me today to image and observe the giant spot 2546 using the homemade 8 inch Newtonian. At 100x the view was fantastic through the eyepiece, with lots of details visible on this large dark spot.

The first shot is similar to what the Sun looked through the eyepiece:

And an image showing the spot in more detail:

And a comparison view showing the size of the sunspot in relation to the Sun and the Earth:

UPDATE (October 2016):

A new processing of the sunspot shot, with a bit more focus on the granulation:
