Details:
Earth's orbit, we know that, is not perfectly circular, and this fact causes a different apparent diameter for our Sun, that is not noticeable (clearly) by naked eye, but emerges easily in this kind of composition. Well, to wait six months to do this kind of composition is a long time, but the results repay everything.
With this comparison we can see how much the Sun is smaller (or bigger if you look at the other image) referring to the other one. And furthermore, we can see the difference between a non stacked and a stacked image, and between a Bridge camera and a Reflex camera.
Different Instrumentations: Nikon Coolpix P90 Bridge in single shot / Canon EOS 700D with Samyang 500mm f6.3 Lens in stack of 30 on 120 - Astrosolar - Elaboration with Autostakkert!2, Registax 6 and Photoshop CC.
