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.
Crop of the Horsehead itself
Crop of NGC2023 showing the details of the reflection componets and HH objects.
Crop of HH Objects just below the horsehead neck.

Thanks for looking,

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.

Yes Stephane,the Creux du Van is a sacred place! I regret i didn't go there, since i have seen your wonderful picture! The Creux du Van seems to be at about 100 km "à vol d'oiseau" from Geneva, where i have gone a few years ago. Maybe i could go, over there, one day:D
The California Nebula of Rolf Geissinger is so great too!!!

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.

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.

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

NGC 2174 (The Monkey Head Nebula)
http://www.emilivanov.com
Copyright: Emil Ivanov 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:
