Galactic Census 2

Normal sudoku rules apply.

Divide the grid into galaxies: orthogonally connected groups of cells that have 180 degree rotational symmetry about their centers (marked with a small dot). All cells must be part of a galaxy; no galaxies overlap.

Grey dots mark "renban" galaxies: those with two or more cells, whose digits form an unbroken consecutive sequence in any order. White dots mark galaxies whose digits do NOT form a consecutive sequence. Digits may not repeat within a galaxy.

There is one "dark star" (a single cell galaxy) that is not marked.

As per Galactic Map Standards: All galaxies with at least TWO cells indicate their SMALLEST digit with a diamond icon. All galaxies with at least SIX cells indicate their LARGEST digit with a circle icon.

The Galactic Census requires that all galaxies with at least THREE cells must report their star system count (sum of digits in the galaxy).
