That is also way incorrect. In fact they don't even use the same glass types for the primary mirror substrate. The Skywatcher scopes are made by Synta and use Pyrex glass as the primary mirror substrate and the GSO scopes use BK7 glass as the primary mirror substrate. Synta is in China and GSO is in Taiwan.
