I'm afraid you're seeing "faces in the clouds"! When the sun is at this angle, the angular features of the crater do cast shadows and make the
crater edges look somewhat artificial. If you examine the crater when the Moon is full you will see there is nothing unusual there. I've never seen
anything odd in the crater myself, and I've been looking at it for many years.
Ok i do see the "pipe" like thing. It does appear to be out of place in the photo it is a lot lighter in color and kind of rounded looking. I
honestly have no idea what it is, but that doesn't say much because I have no expertise in photography anyway.
