The sun through a half-angstrom hydrogen-alpha filter is not the flat disc you have seen in photographs. It has texture, filaments lying across it like scratches, and prominences at the limb that visibly change shape inside a single session.
Ninety minutes in the afternoon, which is otherwise dead time on a site where the real work starts after nine.
