- However Sgr A* is a fairly dormant black hole and may not be illuminated so well, and there is more scattering material between us and it than in M87. A bigger problem may be variability timescales $^{\dagger}$. The black hole in M87 is light days across, so images can be combined across several days of observing.

- Researchers with the Event Horizon Telescope(EHT) project still hope to capture a suitable image of Sagittarius A*, but they’re not quite there yet. So, the EHT team did the next best thing. M87, the supermassive black hole at the center of galaxy Messier-87, proved to be the perfect first candidate for observation due to its enormous size and consistency. Must See : How exactly …

- The Event Horizons Telescope of the European Southern Observatory took inages of both Sagittarius A* and M87 galaxy's black hole. But only the M87 black hole image was released due to the fact that Sagittarius A* is surrounded by thick clouds of dust so image was obscured. However, M87 galaxy's black hole has much much less dust around it.

- That said, I'm not wholly surprised that we ended up seeing M87, rather than Sgr A*, for a couple reasons which the team mentions in their first paper: As Glorfindel said, Sgr A*'s event horizon is much smaller, meaning matter orbiting the black hole has a shorter orbital period. This contributes to variability on the timescale of minutes.
