This is not a new nebula! This nebula was reported by various professional astronomers in 2010, this is the year when the star (also known as HBC 722) had a FU Orionis type outburst and at the same time the yellow reflection nebula was formed. You can read more about the discovery here:

OMG that is EPIC!!! Although very very obscure and unknown, what on Earth made you decide to image this dark nebula?!! It is possibly my favourite of the SL dark nebulae although there are very few that are photogenic. The SL catalogue can be seen here: http://cdsads.u-strasbg.fr/abs/1976A%26A....53..179S

Yes I know but now the nebula is much brighter when ever and visible for all. The FU Ori has a bigger outburst and the nebula are also strong.
For my is new to see this in ngc7000. In 2010 you can`t see this in this form.

LDN 204 needs a much better name. How about the Smokey Lips Nebula?

There's a hint of a sideburn to the right. I wonder if there are nostrils and eyebrows up above it?

Thanks for the compliment. I chose this primarily I was looking for the dark tower which turns out being not far away and I had initially thought this was the dark tower until I took the first frame in Ha. I really liked the shape and I knew it would have some colour in it with the amount of Ha. In the end it seemed a good choice. Now looking to image the dark tower.

Imaged from Tivoli farm in Namibia in June 2012.
Hope you like it!

Caption: A new image of a little-known area of sky in Lupus, at the feet of Scorpion. The Lupus clouds compose one of the main low-mass star forming complexes within 200 pc of the Sun. They contain four main star forming sites, including B228 in Barnard’s catalogue pictured here, more frequently referred to as Lupus 1 in modern literature. It is likely that the Sun formed in a similar star formation region more than four billion years ago. B228 is sometime referred to as the Dark wolf nebula.. I used a long LRGB base totaling over 11 hours of exposure.

To me the nebula looks exactly the same as in 2010. It can be seen in this 2010 image by Joseph Brimacombe: http://www.flickr.com/photos/43846774@N02/4968162388/
Also on your page, it says: "discoverd on 28.07.2013 21.30 UT"
This is incredibly misleading as it was discovered in 2010, here are the CBET reports:
http://www.astronomerstelegram.org/?read=2808
http://www.cbat.eps.harvard.edu/iau/cbe ... 002426.txt

Also this paper that was published in 2011 confirms that the reflection nebula formed along with the outburst in 2010: http://arxiv.org/abs/1011.1647

However there is a possibility that what you say about the nebula becoming larger might actually be true, I'll see if I can get some answers.

Who doesn't love a good old fashioned cosmic mystery to solve?

The Dark Tower is impressive and has been imaged many times, it's easy to image something that's been done so many times. It is much harder to find something new and unique but it add more variety, I hope you get lost in the sky more often!

Also I noticed a hidden secret in your image, a tiny planetary nebula with a size of 20 arcseconds that is known as Sa 3-38, one of its many names. It can be seen near the bottom left corner and I have attached a crop of it.

That is an amazing image of a very rarely photographed dark nebula! It's fantastic that all these obscure dark nebulae are being imaged this summer!! I think there is something that would have greatly improved the image! Since it lies in front of the giant emission nebula Sh2-27, Ha exposures would reveal an overabundance of background emission nebulosity that would contrast nicely with the dark nebula. I'm guessing there's still time to get a few hours of Ha.
