Then add the image of the stars created earlier, and blur it like previously, but 1x1 and select "x". Plug this node into the bottom of the multiply node. Then add an add node and plug the multiply node into it. Then blur the original star image again by 0.25x0.25 and plug this into the bottom of the add node. Then make sure it is connected to the composite node.
