I don't know if I'm the only one but I've had trouble understanding the size differences of different stars when I'm cruising through the galaxy. Yes, you can see the solar radius, mass, class etc. but when you jump into a system, the main star appears to be the same size no matter which system you're in. You can really begin to see the sizes when you're super cruising away from it and turn back from long range

I know this has been done before but here are my comparison pictures edited with some awesome paint skills

. Hopefully you find them mildly interesting atleast! You can see the basic info from the pics, distance is the same: 800 Ls give or take a couple of Ls'. I tried to take screenshots at 500Ls but the red giant filled too much of my screen at that point. This is rather a fast comparison from only one part of space which I'm currently exploring so I didn't find anything between 5-80 solar radius
1st: red giant, 2nd: class C star, 3rd: Class B star, 4th: Class M star

And last sample of my paint art, all 4 put together next to each other:

I knew that the biggest stars in Milky Way are huge beyond comparison but it kinda hit me how huge the differences are when I concentrated on the size of the stars while super cruising. Kinda funny that I've played this from release and only now realized how fricking huge everything really is... As I said, you can't really see it since you get dropped eg 2 Ls away from class M stars and 400 Ls from red giants so they look like they're the same size, atleast to me.
