What advantage did tycho have compared to other astronomical observers of his time?

Tycho Brahe (1546-1601) was a Danish noble man and an astronomer. One of the advantages is that he was an aristocrat and could buy a copy of Ptolemy's Almagest, and some sets of astronomical tables, which showed the positions of the planets at any given time. His accurate observations were based on a large wooden quadrant, part of a circle with a nineteen foot radius, that took twenty men to set up. His very large staff and several sets of equipment permitted four independent measurements of the same thing simultaneously

He was nobel man.

Explanation:

Nobility is ranked right under royalty. This means that Tycho had several privileges, which meant some certain entitlement immunity by the highest authority. That's why he was able to be the first scientist observing space with the heliocentric thoughts.
