Overlapping Galaxies

 The second puzzle here was originally posted exactly one year ago and the first puzzle here was made today. I don't think a name has been suggested yet, so I've decided to name it unofficially in this post.

This puzzle type was invented by yakaki.

Shade some cells and divide the board along edges into regions. Every region contains exactly one clue and has 180-degree rotational symmetry about its clue (like in Tentaisho). Numbers reveal the amount of cells within the region that are shaded. Every mass of orthogonally connected shaded cells also has 180-degree rotational symmetry, about some arbitrary point per mass. 

Variant: Percentage clues reveal the percent of cells within the region that are shaded.
