Star Scramble Mystery Cache

Cache is not at posted coordinates

To celebrate my 3rd geocache hide I wanted to add my previous caches part of this one so I made a nice puzzle that should be fun. Rock solid, Fact hunt (virtual stage), and this cache's virtual stage share a constellation called the ?????? Triangle. Imagine that the geocaches posted are stars and they form this constellation.Type in the constellation's first name without the triangle part into certitude to get the container's coordinates.
