(view directly for a larger image)

or solve online (using our beta test of Penpa-Edit tools where a single star in gray means two stars but the standard Star Battle interface is used; if you prefer seeing 1 versus 2 objects, here is an alternate formatting using mines that allows for that.)

Theme: Stars

Author/Opus: This is the 208th puzzle from our contributing puzzlemaster Murat Can Tonta.

Rules: Standard Star Battle rules with three stars per row, column, and region. Also, there are some shaded cells in the grid and those cells either contain two stars or none. (In a gray cell with two stars, none of the adjacent cells sharing an edge or corner can have any stars.)
