The Alnitak Region in Orion.

This image has taken me since November 12th to finalise, working on it on-and-off. Without a doubt, this has been the most challenging composition as far as capturing (four hours of raw data) and processing is concerned. My right hand is completely stuffed from all the post-processing. I've now resorted to using the mouse with my left hand at work to compensate. I know, I'll probably just end up with two sore arms and a sore back, but, it's all about equilibrium.

I lost all my raw data for every single astrophotograph I've taken. Altogether, about 20 GB of data. Gone. I transferred the data to my housemate's notebook temporarily as I needed the room to process another image. Three days later, his hard drive decided to die of mechanical failure. So, to all those people who requested prints and other products, I'm sorry, all that is for sale is what you will find on my prints page. I'm still coming to terms with my loss.

As for this image:

The bright star to the left is Alnitak, which dominates this region. Alnitak (Zeta Orionis) is located about 830 light years away from our own Sun. It is the southeast most star in Orion's Belt. It has a visual magnitude of 1.7 and an absolute magnitute of -5.3.

The orange nebula in the bottom left is called, for obvious reasons, the Flame Nebula (NGC 2024 or Orion B). NGC 2024 is an emission nebula which is being excited by Alnitak. The closeness of Alnitak makes the nebula hard to see through a telescope. However, with a reasonable aperture and moderate magnification, if you keep Alnitak out of the field of view, you're able to see a soft glow with a prominent dark vein running North to South.

To the right of NGC 2024 is NGC 2023, a dark nebula.

I think everyone knows what the centrepiece is in this image. If in doubt, it's the Horsehead Nebula. The Horsehead Nebula is also referred to as B33, and is a reflection nebula.

The beautiful shroud of pink above the Horsehead Nebula is IC434, an emission nebula.

To the top right is Sigma Orionis, a main sequence star. Surrounding it is an open cluster referred to as SigmaOri.

North is left.

This composite consists of one set of images; one set of 40 images taken at ISO-400..
Each individual image was a 300 second exposure.
IRIS was used to calibrate each image (dark subtraction [median combined master dark] and flat field division [median combined master flat {lights and darks}]), to register, align, and finally stack.
Photoshop CS2 was used to adjust levels, curves, frame and resize the final composite.

It always amazes me how astro shots can be so fabulously different from one another. You're taking the exact same piece of the sky from the exact same angle as everyone else. Anyway this is one of the best of Orion I've seen so well done for really great shot.

Matthew,

Thanks!

This is a very old image. I am going to do re-image this object hopefully this year and do it proper justice (I've got all new equipment since that shot was taken).

IDK If anyone has talked about the laptop failure, but did the computer crash, or did the hard drive crash? Even if the hard drive crashed, the data can potentially be recovered.

i love ur photos. im sorry you lost your data, but im sure you realise that most data can be rescued ! i do not wish to sound condesending, since i do not know if you know, if not with recovery software, there are hardware specialist who take apart the drive and recover everything. it just costs money. i hope you do recover everything, as your photography is amazing and its a real shame to let all that hard work go to the ether. i wish you luck.

:S I feel sorry to hear about your data loss!! :(

I think I have stored most of my photographs (even if they are sucky) on like 3 different places (yay 1 TB hard drive <3) and I still feel scared about losing it.. about 5 years of photos :p

this photo is just stunning, I've been interested in astrology since I was a kid (ok, I'm just 19 now so it's not that long ago) and I have a telescope at my parents home..

I was wondering one thing when I saw this photo (I immediately recognised the horsehead nebula of course ;) no doubt about that); how did you manage to take this without getting those star trails (you know, when the earth rotates, the stars 'blur')

Cześć Ania,

Dziękuję, bardzo.

Hopefully my Polski is OK! It's been many years since I studied it. I learnt a lot just by listening and singing along to Myslovitz. It's a difficult (but beautiful) language to learn. Poland is also very beautiful. I was lucky enough to spend a few days there a couple of years ago, in just Warszawa and Kraków. I look forward to going back sometime in the future.

If you like that image, I have more in my gallery.

Cheers.

Regards,
H

Cześć :)

I'm glad you like Poland, you should come back some day and visit Zakopane, it is so amazing place. I have never been in Australia it is so away... it has to bee beautiful there too.

pozdrawiam
Ania

Ania,

I promise I will. I want to come back and re-visit Poland, Czech Republic, and Slovakia.

Australia is very beautiful. But, not as green as Eastern Europe.

I also think New Zealand is the most beautiful place on Earth. It's simply stunning -- like heaven on Earth. I'm going back there in April and in November for more photography.

Regards,
H

This is the reason why I always wanted to be an Astronom when I was a kid, I love this shot.
I'd love to learn to do what you do.
I'd like to ask you a couple of question if I may.
* Why can't you use 40 times 1 shot of 30 secondes?
* Where can I find some decent tutorials about astrophotography (that includes, buy gear, etc...)?
* What do you mean by "modified" Camera?
Thank you for behing bringing life to my dreams.
