Q is for...

Just for a change, I want you to tell me what the Q is in this photo. It's not particularly difficult and most of you may know it already. Those that don't, it's an opportunity to learn. 

This is a little twist on a previous blip that you may have seen. One that I want to redo because of the great big piece of crap on my camera sensor/lens/mirror or wherever. I will get around to doing that.
