Spiral Galaxy^2 (95)
Instruction:
Place stars in some cells such that each row, column, and boldly outlined region contain the indicated number of different types of stars. Identical stars cannot touch each other, even diagonally. Different stars can touch each other, even orthogonally. Any two different notations can be used to represent the two stars, as long as consistency is maintained through the grid. The usage of black and white stars to indicate the number of stars is arbitrary and can be completely switched within the solution.
