Imaging with the Solar Gravitational Lens (SGL) takes time, as the image is necessarily sampled one gigantic "pixel" at a time. In the meantime, the target, perhaps an exoplanet, rotates and its illumination changes. Can we still reconstruct its surface?
Once the interface loads, press the star (❆) button to create an image blurred by the SGL. Then click with the mouse at random points in this image, to sample it. When you collected a few dozen samples, click, e.g., the right skip button (▶❚), blur it again, and collect more samples. Repeat this several times, preferably at least over a full rotation of the planet. When you think you are done, click the equal sign (⚌) button to see how well the software can reconstruct the original surface of the planet from your samples.
