Nothing to say, I think is one of the most beautiful pic I ever seen before from this area.

That's beautiful. Any chance for a larger version? Would love to use as a desktop.
Thanks for your interest, Alex. Here is a larger version which I used as one of my screen savers. It is 1920x1200, cropped to correct aspect ratio from the orignal.

The color saturation and dynamic range in this shot is nothing short of amazing.

Superb. Excellent example for snobs denigrating DSLRs and insisting on the overwhelming superiority of astroCCDs. Still, a very short integration time for so deep an image.

Here is a link to a astro ccd image totaling 40 hours exposure done by well known astro imagers of the same region.

I think the dslr image is better.

The only tiny criticism I would make is the diffraction spikes around ngc 2023. This can easily be fixed using noels tools. Using per selection only and inverse select.

Hi Bob, Thanks for the comments and suggestions! 
Since the spikes were added using software, I can erase the spikes effects around NGC2023 easily.
Actually there are two much more serious defects with this image which may not be apparent in this reduced size format. The first one is weired and very strong diffration spikes from Epsilon Ori (middle star of the belt). I believe this star falled right on the edge of the sensor or its frame, causing a large blue halo and very strong spikes on the left edge of the frame. It took me a long time to tame it down, but you can notice some trace of unnaturalness around the area if you look closely. 
The other one is that there were some near horizontal spikes on brights stars close to the upper-right hand quadrant of the frame. This is because the frame is extremely close to a power line overhead! It was my fault since I picked a poor spot to setup my equipment. I was very lucky that the power line was not inside the frame and its effects can be largely masked by adding star diffraction spikes on top.
Although I was quite pleased with this image. To be honest, taking this image has a lot of luck involved. Weather on the high mountain was changing rapidly on that night and even rained for a couple of hours. We waited unitl 3am before the sky finally cleared. Then I noticed the overhead power line was bisecting Orion right near M42!  Since I only have about 1.5 hours imaging time left for the night, in stead of wasting time to relocate my equipment, I decided to take my chances and start imaging right away...
