Dear Bill,
In your referenced post here, you indicated " I then looked at the adjacent star near 12 o'clock and one fifth of a Moon radius from the limb (HD 202672). It is an optical double and Fred's wonderful image shows the companion faintly. Pixel scaling gave a distance of 2.84' from the near limb and a time of 01:11:40. "
If not too late ... would you be so kind as to indicate your own "Pixel scaling" determination for the angular distance of the 4 o'clock star (HD 202284) to the Far Limb of the Moon. I think you will agree that we cannot use the Near Limb because it is not well defined in the vicinity of HD 202284.
Thanks in advance
