I love the mod, but, what if the moon could also cause a, purely cosmetic, eclipse to happen in game, something along the likes of the Caelum mod on forge

i think actually decoupling the moon and sun could be cool. moon phases and such would be a problem though as those affect some things (slimes in swamps) in game. it may be better to have that feature be a separate serverside companion mod.

yeah ive also been considering having a second moon have a chance to exist in a world, and its not like moon phases make any sense normally anyway

(i headcannon that theres a giant mirror in orbit, since there should always be lunar eclipse)

spyglass astronomy will never do this because its designed to sit on top of vanilla instead of overhauling anything

this mod that someone else made: https://modrinth.com/mod/astrocraft aims for more realism, so it does this, and may be what you want
