Couple of quick questions on P23 if I may...
When you are initially asked to mark the horizon using fixed line of sight, are you expected to manouevre the spacecraft using RCS so its exact?
Or is somewhere near the correct side of the earth close enough?
Secondly, on one or two of the sightings the star concerned is actually obscured by the LM structure.... making an accurate sighting somewhat challenging!!
Just to make sure my CMC had good data I did an IMU alignment and also a manual SV update before trying again, and same results. Other stars work fine.
Any clue as to what might be going on?
Thanks,
Alex
PS: I am 25 hrs into Apollo 11, so sighting stars 01/02/44/45 EFH/ENH
