You are right but that would be too difficult for me!That has turned out really good.
Although technically the first deaths super laser didn't shoot from out of the center on the dish. The 8 smaller beams around it ended up combining together to form the bigger laser at a bit of a distance. I suppose that would be a lot harder to do.
The death star 2 on the other hand has 7 lasers around the ring with an 8th that does come out of the center.
My sleep meds are kicking in, Ill start getting a bit delusional soon.
