Three experimental starless Oxygen emission images of the Veil nebula
I played with my older material, since the weather doesn't allow new projects.
This time I'm publishing three images of light emitted by an ionized Oxygen, O-III.
Images are closeups from the large supernova remnant in a constellation Cygnus, the Veil Nebula.
I wanted to see and show the actual structure of the nebula, due to that, stars are removed from each image.

Cygnus Trio
Since the weather dosen's support imaging, I extracted an other individual image out of the large Cygnus mosaic. This image shows the same area, than my first ever APOD image, back from the year 2008.
Cygnus Trio
Butterfly, Crescent and the Tulip Nebula
Click for a large image, Note. 1900 pixels and 2,5MB.
Image is in mapped colors, from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Image is shot with the Canon EF 200mm f1.8 camera optics, QHY9 a cooled astrocam and the Baader narrowband filter set, H-a, S-II and O-III. There are four individual panels, each panel is shot three times with different filter for the color image. Total exposure time is around 20h.

Autumn season 2013 opened finally!
Last night I was able to open up my imaging season. After six months mandatory summer pause, it's great to be back!
As usually, this first light for the season is more like a test shot. I need to re collimate my optical path and fine tune my gears for optimal image quality.

First light for the Autumn season 2013
Image is in mapped colors, from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.

Orientation
Butterfly Nebula in constellation Cygnus. This wide field image is taken with Canon EF 200mm f1.8 camera optics, QHY9 astro camera and Baader narrowband fiters. Colors in new detail image are from this photo.
Area of interest is marhed with a white rectangle. More info about this image in HERE.
Technical details:
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack2.
Deconvolution with a CCDStack2 Positive Constraint, 33 iterations, added at 33 % weight
Levels, curves and color combine in PS CS3.
Optics, Meade LX200 12"
Camera, QHY9
Guiding, Starlight Express active optics unit, SXV-AO, and lodestar guider.
Image Scale, ~0,75 arcseconds/pixel
H-alpha 7x1200s, Binned 1x1 = 3h 20min.
O-III and S-II channels are from an older wide field image HERE.
A single calibrated 20min. H-alpha light frame
Image is calibrated with darks and a bias corrected flats. No other processing but nonlinear stretching.

Sharpless objects, 223, 224 and 225 in Auriga, reprocessed
I'm waiting the weather to clear, to be able to open up my Autumn season. While waiting, I have practiced my processing skills, after a long Summer pause.
Sh2-223, 224 and 225
In constellation Auriga, click for a large image.
Image is in mapped colors, from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.

About the new processing
I have used a new technique to dig out a very dim background nebulae. A starless version of 16h H-a exposure is stretched to an extreme and a data in level of background bias is revealed.
To work, images, used with this technique, has to be perfectly calibrated with bisas corrected flats.
The power of this method can be seen easily, if the new image is compared to an older version HERE.
A data hiding near the background level is revealed in this starless image.
This "tone map" is used to boost an extreme dim background nebulae in the final image.
Technical details
Camera, QHY9
Optics, Canon EF 200mm f1.8 @ 1.8
Guiding, QHY5 and PHD-guiding
Imaging platform, LX200 GPS 12"
Exposures
H-alpha, 7x1200s, 13x2400s and an additional
15x1200s imaged with QHY8 and Tokina AT 300mm f2.8
O-III, 5x300s Binned 4x4
S-II. 5x300s. Binned 4x4 .
A single 1200s H-alpha frame
Calibrated, stretched and scaled down, no other processing
This single 20 min. exposure shows how dim this target really is.
There are very few images about this area of sky around.
