I suggest the subject matter of f69v refers to the total eclipse of moon that occurred 26th September 1056 AD as seen from Northern China. This would have been some time after the last recorded sighting of SN 1054 on the 17th April 1056 AD, and may represent a last attempt to determine if it had permanently disappeared at the time of this important event of the year. Once again, the Voynich Manuscript appears to contain the location of SN 1572 in relation to SN 1054.

I suggest the image eye markers may be looking at the two supernovae at the time of the total eclipse of the moon, or rather comparing the former location of the supernova with SN 1572 and the total eclipse, maybe one last attempt to see if it had really disappeared permanently and note it at this important event. The angle of SN 1572 from SN 1054 up through the vertical to Algol is approximately 130 degrees and is the same as the angle of SN 1572 down through the vertical to SN 1054. The proportions are also roughly the same as the distance and angle between SN 1054 and the eclipsed Moon through the Celestial Equator, and SN 1572 and the eclipsed Moon through the Celestial Zero Meridian.

There are only two markers on the page. I suggest that the best fits for these markers are of the orbit of the Moon (main marker locating the total eclipse of the Moon) and the Celestial Zero Meridian (lesser marker), as the eclipse occurs close to the point where the orbit of the Moon and the Celestial Zero Meridian cross. When keeping the same view as above, with SN 1054 central, the orbit of the Moon and Celestial Zero Meridian appear curved. When treating them as straight lines from the horizon to the Local Celestial Meridian then the fit is very close to the markers on f69v, and if the face (red) is moved accordingly to fit the actual orbit of the Moon and Celestial Zero Meridian then it encompasses the Moon’s actual location. Again some distortion from actual positions, probably because it is easier to work with straight lines than curved orbits.
