Partial solar eclipse, Enontekiö

The weather favored the eclipse, only at the very last minutes a dull cloud dimmed the sun. I wonder the orbit of the Sun in the sky in a multi-exposure image, it’s like upside down. To my recollection, Pekka Parviainen answered his picture to the wonder of the orbit of the Sun, that by looking at the hula hoop from its center against the sky, he perceives the matter. The hula hoop didn’t come with me, so I have to ask myself wiser. Images are taken every 5 minutes and the background is photographed separately. The sun should be at its highest in the ninth or tenth image, i.e. around 13:20 but while considering that the camera was probably a bit skewed, it is impossible to get the ninth or tenth image to the top point of the track. Is it the projection of the spherical surface onto the plane combined with the lens distortion correction? The focal length I used in the multi-exposure image was 23mm (MFT), or 46mm (cinema equivalent), and there is no pillow-like distortion in the lens.

Of the larger sun images, I measured the eclipse to be no more than 59% of the Sun’s diameter.
