If you're talking about solar eclipses, read the guide
here.
Anyway from what I gather from the guide, getting 1h handstands down is a big help, but he has a tip in there that'll allow you to balance better even without 1h handstands.
Though, it's an absolute prerequisite that you have to be able to hold your weight on just one hand, especially once you start hopping on it. In that sense I think 1h handstands will help you with that, because it'll strengthen your arm.
