Eclipse MegaMovie is a Google provide to register thousands of images taken during the solar eclipse, to provide spatiotemporal diversity not available any other practical way.
It’s pretty evident this is a laudable first pass. It looks like a lot of photos have over-exposure and dynamic range issues. This could perhaps be addressed by “gap data” techniques. I am excited to watch what imaging amateurs and professionals will come up with from this dataset, to guide future eclipse observations.
One hope I have is that people would become interested in persistent solar observations, using appropriate filters. Currently the nice filters are over $1000, but perhaps a compromise filter can be made much more cheaply.
