I have been reading about the "Time Sight" in several navigation books and find all reference work involves the Sun. I follow how longitude was derived from a single sight by using a DR Latitude. What however was the procedure when working multiple sights as in morning and evening stars,planets or Moon? Did they work up individule longitudes for each sight and then utilize an average Longitude with what I would assume to be a commom Latitude?
