No, see - okay, let me put it like this. An observer is any system that performs an observation, no? Observation is any action/interaction between any two things that cause them to access information (physical, sensory, chemical, magical, etc) about the other and thus detect each of the associated properties (such as electrical charge, mass, momentum, position, etc) to the information accessed, due to being specified by the accessed information, no?

An observer is already relative to something else; the subject that it is observing. This is why I didn't say the word "relative" because I figured that it was already been implied.
