Here are the final results:
In third place was ginge @29. Tied for first making a difficult decision for me, as they were both excellent, were Jono @14 and BBM @ 36. I didn't take Jono's clue as &lit at first; I thought "letter" alone was the definition, but I see that it works both ways. Marty has caught onto the idea that a last minute entry gets attention, but it would be for nought without a great clue. It was a tough choice, but BigBadMarty2 gets the edge with
Tiny fragment of moon found adjacent to star's core (4)
Congratulations, Marty! Here is your prize:

I had already thought of this as a prize, but your clue clinched it.
Sorry, Jono.
