The Propeller Nebula as an anaglyph Red/Cyan 3D
3D-NOTE!
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 many times before, I have turned the image of Propeller Nebula, DWB 111, to an experimental 3D-study.

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

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:
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack2.
Deconvolution with a CCDStack2 Positive Constraint, 33 iterations.
Levels, curves and color combine in PS CS3.
Optics, Tokina AT-X 300mm camera lens at f2.8
Camera, QHY9 Guiding, SXV-AO @ 6,5Hz
Image Scale, 3,5 arcseconds/pixel
Exposures H-alpha 15x1200s, binned 1x1
H-alpha 10x1200s, binned 1x1
O-III 14x1200s, binned 1x1
S-II 5x1200s, binned 2x2
Total exposure time ~10h
Total exposure time ~10h
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

Uh, this is too hard....
I have tried several times but either weather or technique has failed. First my observatory control laptop fried and it took a long time to re install everything.
Now my camera has fried too, just 30 minutes ago. I'll have to send it back to the China but there is a national holiday going on about two first weeks of the October...
I managed to get just a single 20min. exposure before something really bad happened to my cooled astronomical camera. There is a bad tilt in optical axes and other flaws too, I don't count this as a first light.
Single 20 min. exposure of the "Propeller Nebula" in constellation Cygnus.
A new set of wide fields vs closeups
Weather looks kind of good now, I might have something new to publish in few days! I never have had a first light for the Autumn season so late...
Since the weather doesn't support shooting any new material, I have done more image pairs from same target in different focal lengths, usually a 200-300mm camera lens and my old Meade LX200 GPS 12" telescope.
I have done earlier some scale studies from the same material, with Moon circle as a scale.
Now I have done just simple image pairs, showing both, a wide field and a closeup.

A set of wide fields vs closeups
Since the weather doesn't support shooting any new material, I have done more image pairs from same target.
I have shot many targets with least two different focal lengths, usually a 200-300mm camera lens and my old Meade LX200 GPS 12" telescope. I have done earlier some scale studies as a zoom in series, with Moon circle as a scale.
Now I have done just simple image pairs, showing both, a wide field and a closeup from the same objects.

A collection of images from Australia ( Shot by a remote telescope)
Southern wonders
Images from Northern Galactic Groups remote telescope, narrow and broad band. photos.
I had an access to a great instrument, 16 inch RCOS, in Australia for few months about an year ago, what a wonderful experience! I made this poster form presentation from that material. Southern sky is full of wonders and the site was really dark. I miss this "Stradivarius" of telescopes, my old Meade feels like a toy after this...
A labeled version
A collection of remote images can be found from my portfolio, with technical details:
R.I.P Dell laptop at age of ten years...
This was a third time I tried to have my first light for the Autumn season 2011. This time my ten years old Dell laptop, used to run the observatory, died.
I have ordered a new tabletop computer with some extra com ports. There are no 9 pin communication ports in modern computers and many astro gears need one, like active optics unit, TCF-s focuser and Meade telescope control. I bet, the weather will clear up now, since I can't shoot...
Some redone images
I have turned some of my images to a panoramic format for one customer.
They turned to be kind of nice, so I'll publish some of them here.
(They looked wonderful as a large print on canvas)

Moon images from new point of view, set II
Buy a photographic print from HERE
I'm a deep sky photographer and the Moon usually is just an other form of light pollution to me.
The Moon can be a source of inspiration too. (An sometimes good for romantic feelings, I have been told...)
As an astronomical photographer I started with Moon images, as so many do. The 3D-transformation technique of mine gives a possibility to see the Moon from an angle not seen from Earth. This brings a new life to an old Moon image back from 2004.
In this series, some major features in full Moon are seen directly overhead
3D-twisted image, Mare Imbrium seen directly overhead.
3D-twisted image, Crater Tycho seen directly overhead.
3D-twisted image, Mare Crisium seen directly overhead.
3D-twisted image, Crater Stevinus seen directly overhead.
3D-twisted image, Craters Copernicus and Kepler, at lower Right center, seen directly overhead.
At previous post, you will see why I'm playing with old Moon images...
So much about the first light for this season...

I was hoping to be having an opening picture for the Autumn season 2011 here to show...
Weather broadcast for next six days tells it all.

Season opened... kind of
Last night was finally clear! I took my previous picture at March 15., after that, there was no astronomical darkness to work with, since I live at 65N. My first target was the "Propeller Nebula" in constellation Cygnus.
About six months mandatory pause makes no good ones skills and routines. Last night I forget to plug in a power cord of the filter wheel, stupid me. I thought, that I was shooting H-alpha channel, instead I shot four hours of very weak O-III signal. That's OK, I can use it later for a color image, but due my mistake I have nothing to show here, there is very little to see in ionized Oxygen band . (Mainly stars, noise and some very dim signal from the ionization)
Since I don't have anything to show in this post, please, have a visit in my portfolio, there is some re organization done lately: http://astroanarchy.zenfolio.com/
