Exoplanet Transit Detection from Garden Photometry

The most ambitious of the three. Idea is differential photometry: image a known transiting-exoplanet host star continuously through a predicted transit window, measure its brightness against comparison stars in the same frame, and see if a dip actually shows up in the light curve from a back garden.

Realistically limited by the Seestar's aperture and the UK's weather, so a bright, well-studied target (something like a hot Jupiter host) is the likely starting point rather than anything faint.
