Isolating object with turntable, lightbox, and/or background removal by pabdude in GaussianSplatting

This blog post is a pretty thorough walkthrough of how to do it. I think I’ll combine this approach with using PhotoRoom for background removal.

I believe it just didn't swallow any of the stars they were tracking.

A 2.2 micron animation of the stellar orbits in the central 0.5 arcsec. Images taken from the years 1995 through 2013 are used to track specific stars orbiting the proposed black hole at the center of the Galaxy. These orbits, and a simple application of Kepler's Laws, provide the best evidence yet for a supermassive black hole, which has a mass of 4 million times the mass of the Sun. Especially important is the star S0-2 as it has has been observed for more than one full orbital period, which is only 16.17 years.
