Very nice indeed Rob,
That prominent crater in the middle with the twin peaks in the centre
could be Langrenus? Looks a lot like it as I was staring at it the other night when imaging the moon, however I dont know whether that part of the limb is the one that has started to wane (dont think it is, now that I squint really hard to use my brain to remember my reflector flips and mirrors the naked eye view......

)
Very Purty anyway.
Cheers
Chris
