I don't see anything visually, but, I turn my lunar images to monochrome because...

There’s something along the limb at the top of picture but that may just be atmospheric or an artefact in the image. 

Great image btw

You can see it better if I enlarge it

The moon is too high for it to be atmospheric.

For comparison, here’s a pic I took earlier this week. Tiniest bit of yellow fringing on the limb but I’m putting that down to the fact I’m focusing on the terminator.
