Pelican nebula as an anaglyph Red/Cyan 3D
You'll need Red/Cyan Eyeglasses to be able to see this image right.
Note, if you have a Red and Blue filters, you can use them! Red goes to Left eye.

The "Cone Nebula"
Finally a clear night up here 65N!
NGC 2264, the "Cone Nebula"
Ra 06h 41m 06s Dec +09° 53′ 00"
HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
After a long cloudy period we had a clear night. I was able to finalize this target at one night, it'll benefit some more exposures though but I might leave it as it is. Seeing was bad, as usually at this time of year up here, Temperature dropped to -24 Celsius.
The Cone Nebula is an Hydrogen emission region in the constellation Monoceros. Nebula is located about 2600 light years away from Earth. The cone Nebula forms part of the nebulosity surrounding the Christmas Tree Cluster. Note, NGC 2264 refers to both objects, not the nebula alone.
I have shot this object and the Rosette Nebula as a mosaic at Spring 2009, image can be found here:
The Cone Nebula area can be seen at the Left side.
Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.
Technical details:
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations, 50% mix..
Levels, curves and color combine in PS CS3.
Telescope, Meade LX200 GPS 12" @ f5
Camera, QHY9 Guiding, SXV-AO @ 6,5Hz
Image Scale, 0,75 arcseconds/pixel
Baader H-alpha 7nm 12x1200s, binned 2x2
Baader O-III 8,5nm 3x1200s, binned 3x3
S-II is taken from my older wide field image
A wide field image of Cone Nebula used for the S-II channel is part of the mosaic I shot at Spring 2009.
Image is shot with a QHY9 astronomical camera, Canon EF 200mm f1.8 lens and the Baader narrowband filter set, H-a, S-II and O-III.
