In general,
- In philosophy, objectivity is the concept of truth independent from individual subjectivity (bias caused by one's perception, emotions, or imagination).
A proposition is considered to have objective truth when its truth conditions are met without bias caused by a sentient subject.
https://en.wikipedia.org/wiki/Objectivity_(philosophy)
a concept of truth that is dependent on the shared-views from the consensus of two or more individuals based on a framework and system of knowledge.
Note the basis of framework as mentioned by Richard Feyman in Skepdick's link below;

However what is objective within objectivity [as defined] need not be true or factual.
For any claims to be true, factual and real, we need to review whether the robustness of the framework and system of knowledge [FSK] that ensure its output is objective.
Beside the definitions above, the reliability of the objectivity of a FSK must meet certain standards and requirement, e.g. see the 7 Dimensions of Objectivity

There is a wide range of knowledge claims of reality and its truths and facts.
Thus each field of knowledge will be confined to its specific Framework and System of Knowledge, e.g. scientific [at its subs], legal, history, astronomy, politics, MORAL, etc.
To ensure a high degree of objectivity within the framework, there is a need to verify and justify the claim empirically and philosophically within the respective framework and system of knowledge.
I don't believe anyone here will dispute, the scientific framework and system [FSK] provide scientific truths and facts of the highest veracity.
Thus the claims of truths and facts from other FSKs should be compared relative to the scientific FSK in terms of its features, qualities and credibility, i.e. in terms of its processes and reliability of verifications, testing, repeatability, falsifiability of its truths.
Since specific facts are represented by specific FSKs, moral facts are represented by the Moral Framework and System.
The credibility of the facts from a moral FSK will be rated based on its features against the scientific FSK - the standard bearer.
Therefore Morality is objective in the above sense.
