In my judgement, the bit of the reflection with the dot in it, that you
point to with the middle green arrow, is no sharper than the rest of
the reflection or the edge of the spacecraft visible outside the window.

IMHO that particular part looks very much like the adjustment/clasp on a strap or harnass (like the ones you use to secure a load in your truck). I also disagree with the assertion that the parts in quetion are the same focus as the moon in the distance.

I do find it curious that the reflection would be as clear as that, but not have anything else visible in reflection. Is there a possiblity that it was a double exposure or some other effect in the development/scanning process?

Edit: *Shrug* when I look more closely, there does appear to be more in the reflection, but as the intensity of the reflection fades, it blends very well with the moon in the background.
