Looking at the throw angle of the crescent, I would say a standard lens hood would not work. Too wide. What we use on cameras when the lens hood does not help with a flare is what is called a "French Flag" This may help if properly adjusted but why go to all that trouble when a simple matte is what is called for and will work.
Yes, the lens projects a light spill ring but is far out of reach of the main image so we never see it on the screen or a reasonable distance from it.
What I have done is very simple and straight forward and very effective. I only had spill on the ceiling and none noticeable anywhere else except for the far right wall which is flat black duette Hunter Douglas shade. And unless I put up a white card I really can't see it on the shade either. I think if your entire room was projector screen white, you'd see it all around the projector. Anyway, the matte design works well and all traces of lige spill in front of the PJ is gone. I determined the actual position of the matte by displaying a full field screen and then lowered a piece of card down until I just saw the shadow begin to cut off the image. Then I backed off just a small amount and marked it.
OK here's an image of what I did with simple gaffers tape.
The back side of the tape has another piece of half moon stuck to it to prevent the sticky side from touching the lens. The tape does not touch the lens glass.
Also, there are no scratches or mars on my lens or any I can see on the inner elements.
