What constellations did William Baffin use?

William Baffin primarily used the constellations of the Northern Hemisphere during his explorations in the early 17th century. He relied on traditional navigational constellations such as Ursa Major and Ursa Minor, particularly the North Star (Polaris) for guidance. Additionally, he may have referenced other prominent constellations like Cassiopeia and Orion to aid in his navigation. Baffin's observations contributed to the understanding of celestial navigation during that era.
