Linda,
Do you have a citation for the small black and white illustration you posted? The one where you mention the chair. It seems to be a very strong match with the Oresme illustration, BNF Fr 565 fol. 23.
There has been a lot of discussion here regarding cloud band, much of it in one thread that got moved to the "Non-Voynich' section.
Heraldic "lines of division" show the nature of a nebuly line. The crests and troughs are bulbous. The word 'nebuly' derives from Latin 'nebula' meaning 'cloud' or 'mist' and so there is an etymological connection / derivation for the nature of the line and the way it is used - as you suggest. The use of cloud bands in astronomical illustrations is less common than in religious images. And the variation are numerous including certain fire based motifs in the Bedford Master or Hildegard of Bingen.
There are more things to be learned here. Both BNF Fr 565 and BNF Fr 1082 are versions of Oresme's ' Le livre du ciel et du monde' and the two illustrations are potentially equivalent, yet the comparison shows significant differences. BNF Fr 565 fol 23 clearly is an inverted T-O structure, while 1082 is ambiguous. 565 has scattered stars, but 1082 has no stars at all. And again 565 has a classic, scallop-shell patterned cloud band, while 1082 has gone for a much different technique. The VMs cosmos f68v matches BNF Fr 565 fol 23 much better that BNF Fr 1082 does
Meanwhile the VMs Central Rosette matches the scallop-shell pattern quite well, And the second cloud band in the Center Right Rosette presents a different sort of structure that needs further investigation.
