Dark dust in Cygnus, project finalized
This beautiful area is just bellow the North America and Pelican Nebulae. The bright area at upper middle Right, is known as IC 5068.
I selected this as a target, since there is a beautiful dark dust line blocking light at front of the ionization zone and the area is not too commonly imaged. You can see the image in just Ha-light and an image about the relative location in my previous blog post.
Area of interest, just bellow NGC7000, can be seen in this image as a gray scale rectangle.
R=Sulfur, G=Hydrogen and B=Oxygen.
An experimental starless image to show the nebula better.
Technical problems are still driving me nuts... I had to operate nearly everything manually, since my TCF-s focuser and the filter wheel are out of order. Focusing at f2.8 is not an easy task, the critical focus zone is just about 15/1000mm. I had to refocus between the frames, since temperature dropped during the night and I didn't have my temp. compensating focuser operational.
Technical details:
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack2.
Deconvolution with a CCDStack2 Positive Constraint, 33 iterations,
added in about 50% weight.
Levels, curves and color combine in PS CS3.
Optics, Tokina AT-X 300mm camera lens at f2.8
Camera, QHY9 , a cooled astronomical camera
Guiding, Meade LX200 GPS and the Lodestar guider
Image Scale, ~3,5 arcseconds/pixel
Exposures H-alpha 19x1200s, binned 1x1
O-III 8x1200s, binned 2x2
S-II 6x1200s, binned 2x2
Total exposure time ~12h

Dark dust of Cygnus in H-alpha light, a new project
I will shoot other two emission lines as soon as the weather permits.
This area is just below the "North America and Pelican Nebulae". The bright area at upper middle Right, is known as IC 5068. I selected this as a target, since there is a beautiful dark dust line blocking light at front of the ionization zone.
Area of interest can be seen in this image as a gray scale rectangle.
This has been a very frustrating Autumn...
First my observatory PC died. After installing a new computer and all the software, my camera stopped to work. (I'm shooting now with an older model, fixed by soldering and duct tape)
Two days ago, the filter wheel started to act like a lottery machine, now I have to rotate it manually.
Top of that, last night my trusted temperature compensating focuser, TCF-s, refused to work at all.
After five hours of trying to fix it, I did focus manually as well as I could. (At f2.8, the critical focus zone is 17 microns... that's 17/1000mm) Lots of work is done and money spend, just for couple of images. Sometimes I feel, best solution is quit and sell my gears, who ever going to buy this expensive pile of junk. Maybe I feel better tomorrow, after some sleep...

Astro anarchy gets published
My image of the "Wizard Nebula", NGC 7380, get published in the Discovery Magazine.
In October 2011 issue, there is an article about multiverse, and they did use my image with it. Images can be found from a table of content , page 2, and in the story, page 31.
This is the used image. Original blog post, with a technical details, can be found HERE.

Series of panoramas
Images in this post are trying to show, how they looks, if hanging on the wall
I made a small series of panoramas for a printing purposes for a customer. They turned to be so nice looking, that I publish them here too.
Some of the images are meant to be printed as two framed copy, like a sample above, and then placed side by side.
Some of the printed images will be huge, about 200cm x 80cm / copy! Final two frames panoramic pair will be over four meters wide... luckily there are enough resolution for that , with most of my images.
For an example, a price for a high quality framed canvas will be about 300-350€ / one square meter, 100 x 100 cm. ( = ~3.3 x3.3 feet) There are many other framing and media options.
Few sample images on a wall

Bubble Nebula
California Nebula
Butterfly and Crescent Nebulae
Sharpless 119
Sombrero Glaxy, M104
Ps.
I will open up soon a collection of framed samples, in my portfolio. It will make easier to see, how my images might look on the wall.
Any of images in my portfolio, can be ordered as a print, practically in any size.
Imagination is only limit with printing and framing options.
Portfolio: http://astroanarchy.zenfolio.com/p1072219942
Ps.2
BTW. No matter, where you live, since I'm able to use a nearest printing service to your location, to minimize delivery and customs costs.

An animation of DWB 111, the "Propeller Nebula", stars vs starless
The starless version shows the actual nebula. It's funny, how much details one can see from the nebula,
when all stars are removed. An experimental method used for star removal has become very accurate.
Note.
A starlike dot, in up center left, is a planetary nebula PK 79+5.1, a large bluish area,
to seven a clock direction from PK 79+5.1, is a possible planetary nebula PN PM 1-320.
This image was my first light for the Autumn season 2011.
Original blog post, with technical details, can be found from HERE.
Ps.
Above image of the Propeller Nebula, from Cygnus constellation, looks very much like a piece of marble tile bellow.

You'll need Red/Cyan Eyeglasses to be able to see images as 3D.
If you have a Red and Blue filters, you can use them! Red goes to Left eye.
As usually, I have turned the image of Sharpless 119, Sh2-119, to an experimental 3D-study.

Sharpless 119, Sh2-119
Sharpless 119
In constellation Cygnus, Ra 21h 18m Dec +44 00'
HST-palette, (HST=Hubble Space Telescope) from the emission of ionized elements,
R=Sulfur, G=Hydrogen and B=Oxygen.
R=Sulfur, G=Hydrogen and B=Oxygen.
Sharpless 119 is a largish emission nebula in constellation Cygnus. There are not too many images of it around due the close proximity of eye catchers, North America and Pelican Nebulae. Sh2-199 locates just three degrees East from the NGC 7000, North America Nebula. A bright magnitude 5 star 68 Cygni, can be seen at very center of the image above. There are several dark globules at the Southern part of the nebula.
This image covers about three degrees of sky, that's six full Moons side by side. There are some interesting looking structures in the nebula, straight line type of gas formations, they can be seen at Five and Six a clock positions, starting from image center to almost the edge of the image above.
Image is in Natural color palette from the emission of ionized elements,
R=Hydrogen + Sulfur, G=Oxygen and B=Oxygen + Hydrogen.
(Looks much like a "wide screen version" of the Rosette Nebula.)

First light for the Autumn season 2011
Finally!!!
Last night I managed to fix my "backup camera", some soldering and tweaking was needed but it worked out.
My first target was the "Propeller Nebula" in constellation Cygnus.
DWB 111, the Propeller Nebula
Ra 20h 17m 57s Dec -+44° 09′ 20″ in constellation Cygnus
HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Propeller Nebula (DWB 111, MRSL 497). This S-like formation is part of the much large area of emission nebulae in Cygnus. There are very little information around, the origin and distance of this structure is unknown. It seems to be mostly front of the associated nebula. I will make an experimental 3D-study out of this later.
A closeup from the image above.
Image is in Natural color palette from the emission of ionized elements,
R=Hydrogen + Sulfur, G=Oxygen and B=Oxygen + Hydrogen.
Technical details:

An experimental starless image shows the actual nebula better.
Ps.
It looks to me, that there is something going on at Two a clock position in this image. It could be a planetary nebula? There are nearly five hours of O-III in this image, with a fast f2.8 optics, so the emission of ionized Oxygen is not very strong. I couldn't find this feature from PN database, I must study this more later.
Here is a closeup of the area of interest
Just a stretched O-III & H-alpha channels animated
Not much, after about Five hours of exposures. There is nothing visible, about this shape, at S-II channel. Centeroid of the brightest spot is, Ra 20h 10m 39.7s Dec -+44° 12′ 01.9" and the diameter about 360 arc seconds.
UPDATE
Iiro Sairanen, from a Finnish astro group "Avaruus.fi", found this PN candidate from the Simbad database :
http://simbad.cfa.harvard.edu/simbad/sim-id?Ident=%40114921&Name=PN%20PM%20%201-320&submit=submit
It's known under a name PN PM 1-320
