Piotrek Sadowski, your image is just great. It is no secret that I often like bright saturated colors, as long as I regard them as "true", but I really love your subtle colors too. They are so delicate that they almost aren't there, but they really are there, and you have to concentrate a bit to see them. And when you do, it is so obvious that the colors are "true"! :D And the resolution and size of your image is great, too.

(But tell me something, Piotrek. If you live in a part of the world where you can see the Southern Cross at all, you must see it the way it is seen in your picture, with blue Acrux at top and red Gamma Crux at the bottom. Isn't that true? But why is the Southern Cross always shown inverted, then, even in the Australian flag?)

Ann, because the Southern Cross is close to the Southern Celestial Pole it changes orientation through the night quite significatntly. In summer before dawn it looks like this (image from stellarium):

Ann thank you for your kind comments on my photo. Sometimes I fell like I don't belong in the middle of such a fantastic display of technology and imagination. So many photos in this thread are breathtaking!. So your words do mean something to me and thank you for that!

This is NGC7822. I think I'll call it, "In The Maw Of The Monster" :ssmile:
Copyright: Neil Fleming
This is a two-frame mosaic of the region, representing a total of 68.25 hours exposure, including Ha, OIII, and SII, along with RGB stars. I particularly like the ghostly SII areas in the "mouth" of the "monster", to the right of, and near, the dark foreground clouds.

Regards...Neil

Luc Perrot, your image is spectacular! The stars of Gould's Belt look like millions of blue-white sparks being scattered all over the sky by the eruption! Fantastic! I've got to confess, though, that I'm unable to recognize a single constellation, asterism or cluster in your picture - the only sky objects I recognize are the Magellanic Clouds.

And Luis Argerich, your Moon and Jupiter and moons image is splendid! I love the delightfully obvious "Lady in the Moon" in your image (the Lady is looking down and to the left) and I love Jupiter's stripes and its moons!

Six Degrees of Separation
Copyright: Luis Argerich On October 19th the Moon and Jupiter were sepparated by 6 degrees. I wanted to know what can be done with a DSLR camera without a telescope, I was really surprised by the level of detail you can get from Jupiter with just a camera. I used a Canon 550D, a Canon 400mm F5.6 lens and a 1.4x teleconverter. Surprisingly the bands of Jupiter are clearly visible and its moons too. Io and Ganimede are above Jupiter and Europe is below. Calisto is dimmer but is also visible far away from Ganimede if you take a closer look.
Taken at Buenos Aires, Argentina just last night.

Eruption of Piton de la Fournaise under the starry night sky
http://www.lucperrot.fr/
Copyright: Luc Perrot The volcano Piton de la Fournaise, located in the Reunion Island, erupted on October 14. I walked 4 hours in the dark night for realize this picture.
The caldera is illuminated by lava flows.
The starry sky with the colors of fire shows the Milky Way and from left to right, the Pleiades, the constellation of Orion, Sirius, Canopus and the Small and Large Magellanic Cloud.
At the left end of the photo, at ground level, this is not a star. Just an observer with a lamp ...

Here, a picture closest to the eruption : http://www.lucperrot.fr/sa/eruption.jpg

I recently attended the Okie-Tex Starparty held near Kenton, Ok. There were over 400 in attendance. While there I wanted to use the extremely dark skiet to photograph the Gegenschein, which is a very faint glow at the anti-solar point. It is caused by dust in the disk in the solar system reflecting the sun's light back to Earth. This a a stack of 4 10 minute shots taken with an unmodified Canon Rebel XSi. Stacking was done in DepSkyStacker.

It's always nice to have Robert Gendler back with an RGB-image of a spiral galaxy! :D And NGC 7424 is definitely a nice galaxy. It has a short but still very pronounced bar, and the spiral arms that are "attached" to it gives the galaxy's central part a very definite S-shape. I also like the subtle colors here, and the way that the picture brings out the old yellow population "inside the central S", in the bar and bulge region. The galaxy is dominated by a lot of young blue stars and pink emission nebulae along the well-defined arms, and it deserves to be called a piece of cosmic eye candy, certainly in this picture!
