Yes the legs are larger diameter and can spread wider. The top plate is the same diameter and bolt patern for cross compatibility between Meade scopes and it may also be heavier duty in design but I'm not sure?
Basically the giant versions is a much larger and heavier duty version of the standard tripod that comes with the 7", 8" and 10" LX200GPS's
As you can see they are expensive to buy as a seperate item new! I guess the price from an Australian Meade distributer will be well over $1000?

You will notice signifcant difference in stability between the standard field tripod and the giant version, particularly with less than a 12" SCT on it!
