At this location, the Moon started moving in front of the Sun just before sunset. Just before first contact, I took some images with a telescope with a 'white light' solar filter, and also with a hydrogen-alpha (filtered) scope. Then, when the sun was almost at the horizon, I took an unfiltered shot with a 500mm (focal length) scope of the Sun and horizon. Note: if you ever do this, do not look through the camera's viewfinder to frame or focus the shot! This image was my background layer. Even at 1/4000 sec. exposure, the sun was basically a featureless white disk, but the three biggest sunspot groups were visible. The lower the Sun got, the more it became vertically compressed, so when I later superimposed the filtered shots, I had to warp them a bit to make sure they matched the outline.
