    Interesting use of the symmetrical bits to solve this. I admit using a bit of intuition at one point nearer to the end, but thankfully it was spot on.

    1’08. I could probably have saved some seconds by not marking all the unused cells but I lack too much practice on this type to feel confident without marking them.
    About the puzzle itself – excessively symmetric puzzles can be boring but here it made for a fun easy Star Battle, so I am okay with it.
