Leo doesn't have a single right ascension and declination because it's a constellation, a large area of the sky containing many stars.

To find the right ascension and declination of specific stars within Leo, you can:

1. Use an online star chart: Many websites and apps allow you to search for specific stars and provide their coordinates.

2. Use a stargazing app: Apps like Stellarium or SkySafari can help you identify stars and provide their right ascension and declination.

3. Consult a star catalog: Star catalogs like the Hipparcos catalog provide coordinates for many stars, including those in Leo.
