#23 - Moon or Star (2★)

 Rules: Place stars into some empty cells such that each row, column, and outlined region contains exactly 2 stars. Stars may not touch one another, not even diagonally. Additionally, draw a non-intersecting loop through the centers of some cells which passes through each region exactly once. Within a region, the loop must pass through all moons and no stars, or all stars and no moons. The loop may not pass through the same type of clue in two consecutively used regions.
