Abu al-Husayn ‘Abd Al-Rahman al-Sufi (903-986), known also by his Latinized name of Azophi, systematically revised Ptolemy's catalogue of stars. Al-Sufi produced a revised and updated version of Ptolemy's Almagest in a major book called Kitab suwar al-kawakib (The Book of Fixed Stars), completed around 964 CE. Built on the basis of the Greek astronomical heritage, the work of al- Sufi contained a listing of the Arabs' own star names, magnitudes determined by al-Sufi himself, and two drawings of each constellation, one as it is seen in the sky and one reversed right to left as it would appear on a celestial globe. The oldest surviving copy was produced by his son around 1010 CE and is preserved in the Bodleian Library, Oxford (MS Marsh 144).
