Love the orrery. Often when this subject has been raised I've said that I wasn't expecting anything like the concept art, more like an updated version of the maps in Frontier. And that is pretty much what this is. When they first zoomed in on a gas giant and its moons I let out an excited Ned Flanders scream that startled both the cat and my wife, so points all round for that.
As for what this will be used for, as a frequent screenshotter and occasional canyon runner this will be a godsend to me when it comes to quickly finding closely co-orbiting moons, moons close to ring systems or bodies with unusual inclinations giving interesting perspectives. Yes, you can get most of that information from the raw numbers on the old system map, and the new scanning mechanic reveals something of the system's topology as each body is zoomed in on. But for those of us who can't translate the numbers on the fly the orrery will definitely be a useful overview for systems we've newly discovered and, perhaps more importantly, for those whose data we obtain through the new community mapping thing. If I haven't personally eyeballed each of the bodies using the scanner, the orrery in conjunction with the old system map should quickly tell me which of them are worth a visit.
Very much looking forward to the whole of this update. Yes, even with practice the new discovery system is probably going to be a bit slower than the old honk-and-glance at finding ELWs etc. when sprinting. But averaged across all facets of exploration -- honk-and-go, cherry picking and completionism -- it will be much faster overall and should yield a higher cr/h return if that's your bag. If nothing else it'll mean an end to flying 300,000 ls to scan the secondary star and its planets, unless there's something at which you want to lob probes.
And it's certainly embracing the rule of cool. Everything looks amazing.
