This does not work. There's no way that I could have made a louder announcement about the Cassiopeia A expedition (Frontier even published a number of Galnet articles about the event). They knew we were going out looking. We even provided Frontier with a good analog for Cas A located in the right vicinity that they could have just renamed to Cassiopeia A and said, "Good job. We'll take your advice and call this neutron star Cas A."... make sure to announce where you are going first (so FD can hurry put stuff in there to find).
But no ... the final answer from Michael Brookes was simply that Cassiopeia A doesn't exist in Elite Dangerous. Omitting Sagittarius A* would have been just as egregious!
I'm not bitter or anything.
