Murad III
Taqī al-Dīn maintained a strong bond with the people from the Ulama and statesmen. He would pass on information to Sultan Murad III who had an interest in astronomy but also in astrology. The information stated that Ulugh Beg Zij had particular observational errors. Al-Dīn made a suggestions that those errors could be fixed if there were new observations made. He also suggested that an observatory should be created in Istanbul to make that situation easier. Murad III would become a patron of the first observatory in Istanbul. He preferred that construction for the new observatory begin immediately. Since Murad III was the patron he would assist with finances for the project.
