For me its getting my tag on as many objects as I can, OCD and exploration do not necessarily go hand in hand, if I jump into a system and there is an untagged object, I can't leave until I go scan it, no matter what it is or where it is, I have gone 500 k Ls to scan a single icy rock. It sucks, but I can deal with it, at least I get something out of it, my tag will go there. I also like to find extremes as well, or odd systems. I have a system that I discovered with 94 objects in it, now I'm back out looking to find a system with more than that, will take a lot of looking. Came across a system yesterday that had 100, but unfortunately, it was already discovered so it don't count for me, I have to be the first discoverer for it to count, and I have to get all the objects. Took me an hour and half to scan the 94 objects, they were of course spread out all over the place, had 53 rocky world moons in the system. Most system are humdrum and boring, but every once in awhile you run across a neat system that makes it all worthwhile. And since my hearing aint' so good anymore, I have to go and scan an object to see what it is, I don't let my eyes deceive me cause sometimes an object might look like one thing but be something different. That water world I went to scan cause it was untagged, such a pretty blue color, turned out to be an earth like instead, that was a nice find mainly because I wasn't the first one there, someone had been there before me and tagged the main star but didn't scan anything else in the system, it was in an A star system with about 7 objects, all within 2000 Ls of the star, the ELW was the 3rd planet, so about 400 Ls away, was I surprised to get my tag on it, as well as all the other high metal contents and a terra rocky world as well.
Another extreme that I came across and tagged was a planet with the B ring was 19 mil kilometers wide. I mean, I took a screen shot while I was 194 Ls away from the planet and still could not get the entire ring into the picture, the ring began at 6 mil k from the planet and went all the way to 25.2 mil k's.
