I'm too ignorant to answer that, but the technical paper here [https://arxiv.org/pdf/2002.11871] goes into a wealth of detail, and includes an image of Earth as it would appear to such a telescope (before and after post-processing) from 30 parsecs away. The optical properties of the solar gravitational lens are pretty astonishing.

You lost the bet. I've been following his solar gravitational lens project since the 'Direct Multipixel Imaging and Spectroscopy of an Exoplanet with a Solar Gravity Lens Mission' [0] paper came out. What you were betting? You farm, hopefully? [0] https://arxiv.org/abs/2002.11871

https://www.nasa.gov/directorates/spacetech/niac/2020_Phase_... NASA has a whole page about it now. And here's a rather large paper (I remember reading a shorter version, but with the same pictures inside): https://arxiv.org/abs/2002.11871.
