WD40 is considered corrosive in the instrument maker/watchrepair (I have
3 years of schooling and have worked as such).
I would keep it well away from my sextant or any other measuring
instrument that has not been submerged in (salt)water.
IF I was to use it it would be as "emergency fix" and not left on for
more than few hours before completely picking instrument apart to clean
and lubricate it properly using some kind of instrument oil and in some
parts light grease.

However Commander Bruce Bauer recommends use of WD40 on sextants in his book "The sextant handbook" p71 as well as Joel Jacobs from "Land and Sea collection":
