Hi, I did some searching around and found out that the 1 pixel = 1 meter page was actually only one page out of a whole collection with other scales. (10 pixel = 1 meter, 2 pixels = 1 meter, 10 meters per pixel, 100 meters per pixel and 2000 meters per pixel.)
And the bigger ships like the Death Star, Super Star Destroyer, etc, are all here!
