Bert that's great and very topical. It's marked on the Sky & Telescope's Pocket Sky Atlas as the "Dark Doodad".

So I thought I'd have a search for it under dark skies at Snake Valley last weekend. And there it was! Not as distinctive as in your excellent photo, but a binocular object.
Nicely framed image, Bert.

I love the way it starts beside globular cluster NGC 4372 and tracks up into the main Musca stars.
