You're welcome, Emil! Glad I could help you see something in your own picture!
Now it's time for me to add some more comments. I think I'll start with the Moon images, since there are so many Moon images here.
Arbacia, that's a very interesting discussion about the Aristarchus region, and it is a very interesting way to use color to bring out the age and composition of various layers around this area in a fine picture. You also had to work hard to create this picture and interpret what we see in it. Well done!
John Moore (and LROC DTM), that's a rather amazing-looking part of the Moon(?). I would have guessed it was Mars, because that sure looks like old ice or melting ice or something. But the colors represent elevation. Quite fantastic.
Andre Paquette and Dave Rowe, I really like your bicolor Luna. It brings out the redder and the bluer parts of the Moon, and it also underscores the fact that the Moon is somewhat reddish (or more red than blue, at any rate).
Paulo Cacella, that's a fine-looking Moon, very much in true color, I think. You really bring out the smoother and the rougher "texture" of the Moon".
avdhoeven, your Moon image is beautifully detailed, too.
Jaime Fernandez, that's a great closeup of a part of the Moon, and it's a great annotated image!
And now for the other images. François Chevenet, yur black and white picture of the Cone Nebula region brings out that huge arc which is almost "embracing" this whole region of star formation. It looks a bit like Barnard's Loop in Orion, too.
I'm absolutely terrible at reading star trails, Bud Branch, but I can actually discern the Moon, Jupiter and Venus and their very bright trails in your image!
Thomas Jaeger, I've never seen IC 410 look so much like a huge cosmic rose!
Jeff Johnson, how interesting - tiny asteroid Solvejg is flying past the Crab Nebula. Solvejg must be Norwegian, judging from her name.
Rothkko, I love the delicate colors of your Mercury photo. I have often stared at the sunset or sunrise sky and been wondering how the sky does that trick - how it can change from that rich apricot-orange hue into its familiar blue without passing through a "phase" where it looks either dirty or greenish. There is something otherworldly about how the sky changes color. Thank you for showing to us so clearly, Rothko! (And thank you for showing us Mercury, too!)
César Cantú, you have submitted several fine images from what looks like a fascinating trip to a place where there are old temples. I love the "differently-curving" star trails in the first image. I love the Big Dipper and Polaris over Pyramid of the Moon, and I have rarely seen Canis Major look so frisky as in your image Canis Major on Teotihuacan (City of the Gods). You can really see that celestial dog running after Orion!
Efrain Morales, that's a fine Mars image.
Manuel Jimenez, your image is one of my absolute favorites in this thread. I love how you bring out the twisted shape of NGC 3718, and I love the fantastic, luminous colors of your image. You make us see so clearly how the outer parts of NGC 3718 look like wind-blown hair sparkling with new young stars, while the outer parts of the other obvious galaxy, NGC 3729, are sedate. Love that amazing lozenge shape of the bulge of NGC 3718. And I have to say it again, your picture is just so beautiful!
Stefano Conti, your galaxy picture is very fine, too. I much appreciate that you have photographed a pair of galaxies that don't get all that much attention, NGC 4625 and NGC 4618. Your image brings out the many pink star emission nebulae in these two richly starforming galaxies, and we can also see the large, faint outer arms of the otherwise small galaxy NGC 4625. Nothing similar can be seen around larger galaxy NGC 4618.
Michal Kolpak, that's an interesting sky phenomenon: 22° Halo and Upper Tangent Arc! Thanks for showing it to us!
Zach McCarley, that's a fine Venus and Orionids Meteors image. Again I love the delicate, fantastic colors of the deep twilight sky.
Leonardo Julio and Carlos Milovic, I love how you pepper you image with delightful colors! And your picture is full of fantastic details, too. For example, on the left there is a tall, faint but dark structure which stars at the bottom and extends almost to the top. And at upper left there is some faint emission nebulosity.
Mark Johnston, that's a fine portrait of IC 405 and IC 410 and the delightful asterism between them, the Leaping Minnow.
Pascal Drabik, I love the clouds washing in like water between the mountains.
E. Storey, that's a wonderful sunset!
Kent Wood, that's a fine center of the Rosette Nebula. I really like how you bring out the stellar richness in the roundish "hole" of the Rosette. The bright stars are not alone there, but there are many relatively faint stars there too, and many more stars than there are in the right part of the image, for example.
Jaime Fernandez, thank you for the beautifully annotated Mars image!
And thanks to everyone else who contributed images here!
