The star map I generated had a rotation of about 35 degrees (I didn't measure it accurately). The rotation of the stars is 1 degree every 71.6 years, so 35 degrees would put it at about 490BC. Ptolemy in AD150 would have a rotation of 26 degrees. 1420 would make it 8 degrees. This assumes the Voynich manuscript and the modern map are lined up along the same principals. Any angular shift could also be explained by differences between the date within the year the maps are made.

I wonder if the symbols that look like numbers or a date in the bottom figure of 68r1 might have any bearing.
It's hard to tell what the first two characters are, they are small and filled in (it looks a bit like EVA-ol but could also be 04) followed by 9° 9.
Some time back, I looked up eclipse dates in the 15th century and I think there was one on Sept. 9th, but it was later in the century, not earlier, and the numbers (assuming they are numbers) don't necessarily have to be a date (or the record of an eclipse).
The symbol for degrees (descending from the abbreviation g° = grado/grade) had been in use for some time.
