Details:
AR 2673 is preparing for departure in this shot. As it goes towards the limb its shape is distorted like the hot air distorts far away objects during the summer days. This shot was acquired in poor seeing with the 8 inch Newtonian and full aperture filter.

Amazing detail of a fantastic active region. I am not sure that the shape is distorted as a mirage might be. Foreshortening occurs because the sun is a sphere; this is the Wilson effect: https://en.wikipedia.org/wiki/Wilson_effect.

Thank you John! Well, it was just a comparison with the effect, not the true physical phenomena behind the effect. I know of course about the true behind the apparent distortion of a sunspot towards the limb.

Either way, it still looks pretty twisted, in my inexpert opinion :)
Great shot! Thanks for posting it
