In reply to ANN's comment: Kinch, that's an interesting portrait of cluster NGC 2259, but it's an even more interesting portrait of that nebula. I thought at first that it was a reflection nebula because it's blue, but it is an emission nebula taken through Ha/OIII/SII filters. Does the blue color mean Ha here? Because if it means OIII, then whatever ionizes that nebula must be very powerful. Well, interesting, in any case!

There is both Ha & OIII emission. My web page is now updated to show the amount of each....about half way down the page: http://www.kinchastro.com/ngc-2259.html
