zema88, that is a very elegant portrait of the Pleiades, particularly in view of the non-favorable weather conditions. And it is a lot of fun to see the asteroid among the sisters!
Michael Siniscalchi, I so rarely like pictures of planetary nebulae, but I like yours. Your portrait brings out many interesting structural details in the nebula, and I love the colors. The nebula is red, pink and dust-brown, and in the center there is that deep dark blue-green hue from a bit of oxygen emission. It is interesting to see that the central star of the nebula is by far the bluest object in the picture, which is what we would expect from such a hot object. Interestingly, though, the blue color is slightly tinged with green. Is it possible that the green color of the OIII emission, through which we see the central star, affects the apparent color of the blue-hot white dwarf? I'm asking because there appears to be a spiral galaxy peeking though the central "hole" of the planetary, and the galaxy appears suspiciously greenish, as if its color had been affected by the thin green-glowing gas in front of it. Well, very interesting in any case!
Adam, your image is great, like all your deep-space pictures. Since the Orion Nebula is perhaps the most-photographed deep-space object of them all I'll refrain from commenting much on the picture, except to say that the colors are very fine and the structural details beautiful. I particularly like the dust lanes in the nebula called M43. These dust lanes almost look like a network of fine arteries. However, the detail I find most interesting is the distribution of small stars in the deep red background. In some parts there appears to be a wealth of small stars, but in other parts there are far fewer of them. I have to wonder if the small stars are background objects, which in some places can be seen clearly and in other places are hidden by dust, or if they are the products of earlier bursts of star formation here.
Nicola Montecchiari, that is a very beautiful portrait of the Eta Carina Nebula, particularly the high-resolution image. I like how you bring out the different color and texture of the different "lobes" of the nebula. I like the impressive appearance of the great NGC 3293 cluster in the far left corner of your picture. The cluster looks very rich, and some wisps and tatters of all the gas that went into making it are still visible around it.
