I think they are both equal. I do not think that Celestia is more powerful. I do agree that Celestia can control her power better than Luna because she’s had 1000 years more practice than her. But I think Luna can control the sun and moon, just like celestia. They are sisters- same blood, same amount of power. If celestia was more powerful and could control the sun and moon forever then why was Luna created? Luna has a purpose, she is needed. Therefore she has a power that Celestia does not understand. Just like Luna doesn’t understand Celestias power.
