Is this Sony 20mm F1.8 too decentered or good as can be expected?

Title says it all. Purchased a new Sony 20mm F1.8 G. As reviewers report -- lens seems always sharp in the center. Edges could be better. Is my sample below too decentered, to the point that you would exchange it? Or is this really close to the best you could hope for? It will mainly be used for Astro -- so wide open is a concern. I assess the right side to be consistently better than the left (contrast and sharpness). I pasted a few examples with this post, but I have many more and it is a consistent pattern.

These lens purchases are big money for me, so I think I stress about it more than a normal person.

All shots here are wide open and the right side remains a bit better through 5.6

Some of the images may be randomly dark from passing clouds etc    Settings were kept the same for each group.
