However, during the latter pa.rt of the flight with a quarter Moon, we found that there were more stars visible. We have a d:rawing here of the number of stars we could see in the Pleiad.es, which b.&e been recorded. Lovell The big thing to remember here is the fact that the Moon has a big effect on the number of stars you see and which ones you can use for celestial navigation. Borman Right. Lovell If the M::>on is full, it is the predominant feature in the sky, and s:n:y stars near the M?on at the time are washed out; and they are very hard to use for sextant sightings. Borman Right.
