I took this image over two nights on Feb. 8 and 9th 2011. The total exposure time was 13 hours trough Ha, SII and O III narrowband filters.
The colors are mapped to represent near RGB look. Image deatails and the same image in HST palette can be seen here:

Hello Celine,
You can easily access at the Creux du Van by the refuge of Soliat ( http://sites.google.com/site/lesoliat/Home ), you must wait the summer that the road is open, 1h30 from Geneva and 0h30 by walk to the top, the « tomme of Soliat » is unforgettable

Alex Cherney, that's a great vimeo!

I was glad to a nice RGB image of the interesting galaxy M106, NGC 4258. It is known for its water masers, which apparently originate from its central black hole. I think its distance has been determined thanks to those water masers, too. Myself, I particularly like what I learnt from old James D. Wray, namely, that M 196 has a "fossil" arm (or a "fossil patch", perhaps). It is the aqua-colored patch just below the row of pink emission nebulae at the upper edge of the yellow disk. The aqua-colored patch is dominated by the light of A- and F-type stars, but it contains few B-type stars and no O-type ones. It is a "post-starburst" part of M 106. But as you can see, the star formation continues along the pink emission nebulae above the fossil patch.

The picture of the Small Magellanic Cloud is unusually nice, too. It is beautifully resolved and really shows off the emission nebulae of this diminutive galaxy. On the other hand, it also shows the rather large part of the galaxy where no new stars are being born. As far as I can understand, much of the gas that used to belong to the SMC has been driven out of it, mainly because of interaction with the LMC.

I like the "star color image" of Orion. Rigel is noticably less blue than the other bright blue stars of the Hunter. To me, one of the "bluest experiences" of Orion has been Lambda Orionis, at the upper right of salmon-colored Betelgeuse. Lambda Orionis looks satisfyingly blue here. Also note the little red star to the right or upper right of Orion's Belt. There is a carbon star about there, and it might be called W Orionis (but I don't have the energy to look it up right now) and it is a nice star, though it doesn't look all that red in the eyepiece.

Ken Crawford and Robert Gendler, ... your images are very nice, and I particularly like the image of NGC 2023. I haven't seen closeups of that nebula very often, and details in your image are great, Ken.

Martin,

Thanks for this information. If the mag 12 star referenced has an annual proper motion of 0.229" in DEC, then the movement over four years would have been 0.916" or, at your image scale, just over one pixel. The actual movement looks a bit more dramatic than that, but maybe it isn't.

The California Nebula of Rolf Geissinger is so great too!!!

This is an experimental image. I captured 35 non-guided images of Orion, beginning with a completely defocused one. The star discs were very big and diffuse. After exposure, I set the focus via remote. After 17 images, the focus was exact and the stars were small points. After that the game began anew so that the discs grew bigger. The motion of the stars were from the left to the right. Nice to see: the colours of the stars.

Combining 8 hours of Ha into 9 hours of LRGB helped bring out the structures in the background curtain of IC434, Ha regions of NGC2023, and the Herbig-Haro objects.

Thanks for the nice comments. The fast moving star has been known for a while, see the following link: http://articles.adsabs.harvard.edu//ful ... l%20br%20/
The picture was recorded using a ST10XME CCD Camera camera and a telescope focal length of 1600mm, which results in a resolution of 0.88 arc-seconds/pixel. The first picture was taken on 26.12.2006 and the second picture on 29.01.2011.

Celine and Ann, thank you for your nice comments and sorry for my broken English, it's of course, the Milky Way over the Creux du Van, a place also sacred as Uluru ...

As for the red star that is moving in the Crab Nebula image, do you think it could be an 11.7 magnitude star designated TYC 1309 1640, whose proper motion is given as -61 ± 2 milliarcseconds/year in RA and -239 ± 3 milliarcseconds/year in dec? The color of the star is given as B-V = 0.954 ± 0.243, which seems reasonable based on the appearance of the star. No spectral class is given for the star, but it could be a small main sequence K-type star, perhaps even a halo population star whizzing by us fast, like Arcturus does, though Arcturus is so much bigger. And Arcturus is a lot faster, too.

I agree with Céline that Nuitsacrees' image, Milky Way other The Creux du Van in Switzerland, is stunning. It's fantastic to look at the larger version of it and pick out lots and lots of objects in the Milky Way and its surroundings: The Beehive cluster, teh Tau Canis Majoris cluster, the Rosette Nebula, the Lambda Orionis nebula, the Alnilam association, M35, the Pacman nebula, the Crab Nebula, the Flaming Star Nebula, the Pleiades, the California Nebula, M34, NGC 752, the Double Cluster, the Heart and Soul nebulae, the Andromeda galaxy, even M33... And the wintry Earthly background, with the sedimentary cliffs with many geological layers but also evidence of life (the trees!) is stunning, too.

Martin Fiedler's Crab Nebula animation is fantastic, like a beating heart.

Rolf Geissinger's two versions of the California Nebula are fantastic. The natural color image is a bit more beautiful in my opinion, but even I have to agree that more details can be seen in the Hubble palette image. Rolf has gone to the trouble of seeing to it that the stars are not pink in his Hubble palette image - thank you so much for that, Rolf!

I like Reinhold's Rosette Nebula image, too, with its fine star colors!

I see that one too. Also -- and more difficult to find -- the brightest star just outside the nebula at about the 3 o'clock position has a tiny spot appearing at its upper edge and then disappearing. Possibly an image artifact, but perhaps a binary peeking out from behind its primary?

Hi,

this is my Rosette Nebula from 2011 with Starlight Xpress H36, 12" Newtonian, LRGBHA=240:240:240:240:300 minutes with 15 minutes subframes.
Enjoy the Rosette.

Martin Fiedler's M 1 GIF is very interesting. A star is also moving at the lower right. Does this reflect real motion over a 4-year period?
