NGC 7129 is a fantastic starforming region! There is just such an amazing amount of fascinating details to see in it. Little red arcs which are likely bow shocks at the ends of jets of small low-mass very young and not yet fully formed stars, long "rope" shapes in various parts of the nebulosity which are likely caused by magnetism (or so I think, but I may be wrong), blue reflection nebulosity with ionized hydrogen alpha red rims, coal-black extra-thick pockets of dust and deeply embedded dust-reddened (and therefore orange-looking) stars.

What a great image! Thanks, Adam!

Wolfgang, I can see that you are online now, so let me say that that is an interesting image of NGC 1491. I'm not too sure of what kind of nebula that is, but I note its interesting colors. The interior of it is magenta as if the color is a mixture of blue reflection nebulosity - testifying to the presence of dust relatively close to the hot star - and ionized red hydrogen, testifying to the presence of a hot star, probably at least of class B2. The nebula is surrounded by a red rim, which may possibly be more highly ionized and brighter than the interior of the nebula because it "collides" with the interstellar medium.

That's an interesting image! Thanks!

Mario, that is a beautiful image of the Pleiades -- not too florid in colour, yet showing plenty of detail in the gas cloud. Great work.

Danish Draconids 2011 and Aurora

Short 4 sec. exposures (light sensitive) and a light pollution filter made this picture possible in the moonlight glare.
The Aurora came as a surprise, just for a few minutes above central Norway, it was photographed from Denmark (500 miles away).
Shot over 1400 photos between 20:18 and 22:32 local time (UT+2), oct. 8th. 2011.
During that time 14 colorful meteors is caught, as seen in this composite photo.
Canon 1D IV, 24mm f/3,5 TS-E and a baader Moon & Skyglow filter.

Jesper, I'm always glad to see you here. The Draconids looked about that way to me, too: they were fairly few and faint, but there was an occasional bright one. (For me there was exactly one bright one!)

And I didn't get to see an aurora!

That's a very beautiful picture, Jesper! It's like a splendid picture of what my night could have been, if it had been many times better than it was. I still recognize my onw night in your image!

Mel Helm, that a beautiful image of a wonderfully delicate structure, the Bubble Nebula.

Jason Jennings, I like your Pipe Nebula, but tell me: Is that blue star Theta Ophiuchi?

Thomas Davis, that's a fine picture of the emission nebula ionized by one of my favorite stars, Gamma Cassiopeiae.

Leonardo Orazi, I want to thank you, belatedly, for your very fine picture of NGC 205, one of the satellite galaxies of the Andromeda Galaxy. Note the tidal tail of stars stretching away to the upper right in this picture, probably in the direction of mighty Andromeda!

But note, too, the interesting characteristics of NGC 205. Far from being a featureless boring yellow blob, NGC 205 sports dust clouds close to its central region. And inside the dust, closer to the center, the stellar population is bluer than elsewhere! We are clearly talking A- and F-stars here, whereas the rest of the galaxy is dominated by K- and M-type stars. Obviously NGC 205 underwent a smallish burst of central star formation a few hundred million years ago. Thanks for making that clear in your very fine image, Leonardo!

Thank you so much Ann ... a challenge realization for me ... so hard to manage in colors.

All the best,
