So in 1.17.1, when you're not using the spyglass, stars appear as normal.

Small tiny, as they should.

But when you do use the spyglass... well.

Stars should not scale like this. This is terrifying on an existential level. Pls fix.
And thanks for the mod~♪

I'm not sure what the bug is here, the stars are rendered at a fixed distance from the player like a skybox. You'd get the same effect with the vanilla star rendering.

You could just reduce the overall size of the stars.

This is terrifying on an existential level.

Well, you are playing a game where everything is some form of cuboid. :)
