OAG prism chip

I noticed a VERY small chip on the bottom edge of the prism of my OAG - about 0.5mm wide and about 0.25mm high into the prism.

Is this going to affect imaging AT ALL by presenting an odd diffraction surface, or is the prism sufficiently forward of focal point to be inconsequential?

I know I can buy a new prism from TS for it, but of course do not want to. I also cannot try it yet, as my proper adapters have not arrived

Paint the chipped bit dark (marker) so light doesn't pick it up as a reflection and you'll be good to go.

I just ordered a new prism from TS - I mean 9 Euro won't break the bank, and I softened shipping by ordering another adapter too.

Will blacken it with a fine point sharpie anyway and see how that goes. Merci Marc.
