We do not know because we have not found any of his writings yet.
Ptolemy believed he was right in his geocentric model of the universe because it provided a coherent framework that accurately predicted the positions of celestial bodies as observed from Earth. His model, outlined in the "Almagest," incorporated complex systems of deferents and epicycles to explain the apparent retrograde motion of planets, which matched observational data of his time. Additionally, Ptolemy's work was widely accepted and influential for over a millennium, reinforcing his confidence in its validity.
Yes, Ptolemy could be considered a successful astronomer. No history of astronomy would be complete without citing his early work. Though he lacked anything that we would consider as an astronomer's tool, he had a marvelous mind with which to consider the heavens. He took observations and wrote the Almagest(The Great Book), which is a monumental work in earliest astronomy. Use the links below to learn more.
Ptolemy developed several mathematical models to describe the motions of the sun, the moon, the planets and the stars. The book that describes these models is called "The Almagest" or "Ptolemy's Almagest". The models all assume: 1. The earth is stationary. 2. All objects travel with uniform speed on a perfectly circular orbit. However, a model that placed the earth in the centre of the orbits of all other objects would not work because it does not account for various anomalies, including the varying length of seasons, the irregularity of eclipses of the moons and the retrograde motion of the planets. Ptolemy used two mathematical devices to deal with the anomalies: eccentricity (an offset from the centre of a circle) and epicycles - circular orbits whose centre (or eccentric) itself traveled in a uniform circular orbit. Much of the material in The Almagest was already known to Greek astronomers. Ptolemy's contribution was to consolidate all known results, make large improvements to the models, and to write it all down in a way that became a standard for the way to present the results of scientific enquiry. His book was the standard text book for astronomers until his models were ultimately improved by Copernicus, Kepler and Newton. Ptolemy also wrote a treatise on Astrology, based on his deep knowledge of the motions of the heavenly bodies. This work is called The Tetrabiblos.
Cleopatra's brother were Ptolemy XIII and Ptolemy XIV.

The Almagest, a treatise on astronomy was written in the second century A. D. Its author, Claudius Ptolemy, lived in Egypt and wrote in Greek.
An almagest is a comprehensive treatise on astronomy, alchemy, geography and/or mathematics, originally referring to the one compiled by Ptolemy around 150 CE.
Assuming that "algamest" is a typo/misspelling of "Almagest", Claudius Ptolemy.
In 150 AD, Ptolemy published The Almagest This book was basically a summary of all the astronomical knowledge the Greek civilization had accumulated through the years. It included a listing of over 1000 stars and named 48 constellations. Those 48 constellations formed the foundation for our present constellation system.

Almagest is an astronomical manual written in 150AD by ptolemy, the date it was published is unknown. it served as a guide to astronomers in the early 17th century. The almagest is divided into 13 books. Each book is an argument on a different topic in the solar system. The Almagest also contained tables containing the exact position of planets at any given time. It was one of the first manuals written studying astronomy.

It was named well before Ptolemy listed it in his Almagest in the second century.
