I watched this video before I had the credits to buy a Phantom. I then set a goal which took weeks to reach - engineer the best possible Phantom (or ASPX if it turned out I didn't like the Phantom when I tried it) that was resilient to whatever the galaxy could throw at it, and then take a scenic route to Sagittarius A*. Reaching that goal made me do things like mine 500 units of something and other stuff to get access to engineers. While the laser mining was dull, the trading with 50 markets was fun, I made a ton of credits and got me to Tycoon trader - one short of Elite. On my way to Sagittarius A* I sold some exploration data at a
DSSA carrier and gained Elite rank in exploration. So I arrived at Sagittarius A* in my idea of a perfect exploration ship as an Elite explorer

I spend ages playing with the light lensing effect of the blackhole, and returned for a second visit in the orange Orca a short while ago.
The benefit of reaching Elite rank is you get a permit to access the
Shinrarta Dezhra system and Jameson Memorial space station where every ship and module in the game is available at a 10% discount. I made Elite rank weeks ago, and I have not been to Jameson Memorial yet

Too busy in Colonia and exploring.
There are some other blackholes on the route to Sagittarius A* which are well worth visiting in their own right, but also serve to give a greater sense of scale for the supermassive blackhole at the galaxy core.
One of my favourites is at a tourist destination known as Black and Green.
