Reprocessed to remove all foreground stars (as far as possible) which leaves just the nebulae contained within M33 Triangulum galaxy. This is a very unusual image, something of a crazy idea to create a pure narrow band image of another galaxy (nobody does this!) designed to reveal nebulae in a 3million LY distant galaxy. I thought it turned out very well.
