He was aware of European advancements in astronomy and did acquire and consult European astronomical tables, including those compiled by French astronomer Philippe de La Hire. Reproducing such tables, like refraction tables, was part of his effort to create accurate z\u012bjes (astronomical tables). Statement 2 is incorrect: While Sawai Jai Singh built sophisticated observatories (Jantar Mantars) with large masonry instruments, these were primarily designed for naked-eye observations to measure astronomical positions accurately. There is no significant evidence to suggest that his astronomers developed or regularly used telescopes for observations like the lunar phases of Venus.
