Enjoy!

Hi Ann:
The reason that the image is not opened, it is because my web site hacked, but now has been restored.
Thank you very much for your words and for saw the picture.
A large greetings
César

Okay, time for me to post more comments!

I'm not much of a Mars girl myself, but I think those are very fine Mars images, Efrain Morales. There is a lot of detail and color contrasts there.

Ah, Marco Angelini, Fabio Tagliani and Francesco Antonucci, what a lovely NGC 2264 cluster, Cone Nebula and Fox Fur Nebula! It's positively sparkling with color, and it looks truly festive. This complex is sometimes called the Christmas Tree cluster, and you have made it look fit for a holiday, indeed!

Markus Noller, that's a very fine Flaming Star nebula! Welcome to Starship Asterisk!

Manos Kardasis, that's a fine Jupiter and Ganymede! It's interesting to see how you have brought out detail on Ganymede.

Juan Carlos Casado and Daniel Padron, I must say that your Star Trails Panorama is one of my favorite images in this thread. It is incredibly decorative and quite amazing-looking!

César Cantú, for some reason your Sun image won't open to me right now, but I have looked at it before and admired it. It is incredibly full of amazing detail. I remember that I could see what looked like the granulation of the Sun, and then there were long, dark, straight filaments. It's a great image!

mat, I really like your wonderfully starry star field of the Double Cluster in Perseus, h and Chi Persei.

Mike Brady, welcome to Starship Asterisk*! You have posted three fine images.

Paul Haese, I obviously like your image a lot! It is so blue... And then there is a lot of fascinating dust structure, and the stellar embryos look very fine below the dust-enshrouded double star above the other blue star. I like the globular cluster, too.

bladerunner, that super-colorful California Nebula really appeals to me!

Dan Watt, I like your Cone Nebula wide field. The well-known Cone Nebula and Christmas Tree cluster looks almost "embraced" by friendly "arms" of nebulosity, like a mother embracing her "baby".

Jerry Lodriguss, that's a great Gemini to Auriga image! I love how you bring out that many of the nebulae and clusters appear to belong together in distinct "cities of star formation". For example, Sh2-249, IC 443 and M35 almost look like "pearls of a horse-shoe shaped string". Your full resolution annotated image is fantastic!

Nicola Montecchiari, your image also wouldn't open to me, but I found some great images on your homepage. Very well done!

Alessio Pisani, that's a fine Pacman nebula.

Craig and Tammy Temple, I love your Thor's Helmet image. That blue bubble looks fantastically delicate and beautiful.

Joe (sullij1) Sullivan, that's a fine NGC 7000 and IC 5070.

Lynn Hilborn, you did the obvious and imaged the Orion Nebula and the Running man nebula. You did it very well, too!

Wolfgang Promper, that's a fine M13 image and a fine M101 image, too!

Thanks to everyone who posted images here!

Ann

Thank you Ann for you appreciation.
I've quite a lot of data to process.....
To the next!

NGC7000 AND IC5070 by Sullij1, on Flickr

North America Nebula (NGC 7000) spans about 50 light years and lies about 1,500 light years away toward the constellation of the Swan (Cygnus). The North America Nebula is large, covering an area of more than four times the size of the full moon; but its surface brightness is low, so normally it cannot be seen with the unaided eye. The North America Nebula and the nearby Pelican Nebula, (IC 5070) are in fact parts of the same interstellar cloud of ionized hydrogen (H II region). Between the Earth and the nebula complex lays a band of interstellar dust that absorbs the light of stars and nebulae behind it, and thereby determines the shape as we see it.

It is belatedly time for me to at least start my comment post. As usual, there are a lot of great images here!

I'm going to start with Adam Block this time, because he has two images here, and he is one of my great images because of his fantastic dedication to imaging the sky. If you want to see a nice RGB image of a celestial object, chances are that Adam has photographed it and posted his images for us to see.

Adam's image of handsome galaxy NGC 7184 is up to his usual standard. The galaxy appears to be barred and present its bar to us end on. Note the two dust lanes that appear to connect the obvious ring structure with the bright nuclear region. Such dust lanes are typical of bars. Note, too, the slightly pinkish hue of the ring, which suggests that relatively widespread star formation is going on here.

While the portrait of NGC 7184 is handsome and interesting, Adam's image of interacting galaxies NGC 2798/2799 is stunning. Galaxy NGC 2799 appears to be plunging headlong into the nuclear region of larger galaxy NGC 2798. During its fall, NGC 2799 has set off a fantastic starburst activity. What is not brilliantly blue in this galaxy is brilliantly pink from huge emission nebulae. Possibly we can see where the center is in this galaxy, since there appears to be a sort of brightening and thickening of the galaxy on both sides of the brightest pink knots in it. In this thickening, we are indeed probably seeing a non-blue and a non-pink population. It is probably the bulge of this galaxy, dominated by an intermediate population.

As it plunges towards NGC 2798, NGC 2799 has probably already managed to dump a lot of gas straight into the central parts of the larger galaxy. NGC 2798 has reacted by setting off a tremendous starburst in its central area. Note the incredible large pink knots to the upper left of the nucleus. Note how brownish filaments of dust are either plunging straight into the nucleus of NGC 2798 or else being flung up from the nuclear area. Perhaps both things are going on at once.

Note, too, that the "body" of NGC 2798 is intermediate in color. Little or no star formation has been going on in the disk in NGC 2798 for a long time. This galaxy was probably on its way to settling down, when it encountered the interloper NGC 2799. What an incredible encounter!

Finally, note the blue galaxy UGC 4904 to the left of the interacting pair. This magnitude 15.2 galaxy sported magnitude 13.8 supernova 2006jc a few years ago.

Let's continue with the galactic theme! Wolfgang Promper has submitted a very fine image of the fascinating galactic pair, NGC 3718 and NGC 3729. NGC 3718 is the large, blue, diaphanous galaxy. Everything in it is delicate and transparent except for the dust lane. Two arms appear to extend from the dust lane and point "straight and unbendingly" to the lower left and upper right. Note the fantastic group of distant interacting galaxies to the right of NGC 3718.

Davide Bardini has submitted two very fine "galaxy field" images. I particularly like the first one. I like the brightness (and the fine blue color!) of the star Phecda, gamma Ursa Majoris, an A0 type of star a little more than 80 light years away. How nicely it contrasts with fine spiral galaxies M109, about 70 million light years away, and NGC 3953, about 64 million light-years away.

Jesús Vargas and Maritxu Poyal have submitted a fine image of M81 and M82, with some fantastically red Ha emission from M82 and a lot of intergalactic gas and dust. Terry Hancock has made a similar portrait, which brings out the large golden bulge and silvery arms of M82.

cybermystic99 has made a portrait of the field around bright star Caph in Cassiopeia. The picture doesn't look like all that much, until you enlarge it and find elusive, dust-reddened, starbursting nearby dwarf galaxy IC 10 as a reddish smudge at center left. Fantastic!

Finally, chapdelaine has processed data collected by ESA/Hubble and produced a very fine picture of galaxy NGC 3081 in Hydra. Note the bright yellow nucleus and inner yellow lens, which appear to contain a bar. Note the bright ring around this yellow nucleus and lens. Note the fantastic, faint, delicate, transparent yellow oval outside it, and the brighter blue "oval ring" outside the faint yellow oval. What a fantastic galaxy!

And now I'm afraid I have no more time, so I'll have to come back later.
