What will you fill in for #?

Solution

Black filled star.

Each row and column has to contain each kind of pentagram.

Also: I think it is the diagonals? Similar to determinant rule application.

There are multiple potential ways of solving this, and I concluded early on that "nah, it can't be that simple". So I went through the ones I could think of just after waking up at the crack of noon.
Row sequence.
Column sequence.
Diagonal sequence (with wrapping).
They all came down to a simple XOR, so Black Star.

can you expand on the xor reference? I do not see the connection to boolean logic? You mean its an all unequal relation for rows and columns?

For instance, compare the first and second columns. When you examine corresponding segments of the two stars, the third column will be shaded only if the segments in the first two stars differ in shading. In other words, it behaves like an XOR operation.
