Hi Al- well well well, certainly worth waiting for: a magnificent first flowering. Your culture must be excellent. I got one before I was ready and totally inexperienced: it gave one wonderful flower, but only the one. I soon managed to it send it into a terminal decline, I'm afraid. (Thankfully, I am better with the Oncidiinae than I was then!) So I salute you!
And this is a stunning plant- it can never be old-hat! I can never see enough of it!!
