IC 63, a ghostly figure
A nebula in a Halloween theme...
IC 63, an emission nebula in constellation Cassiopeia.
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.
Nebula is next to the Gamma Cassiopeiae, a bright, mag. 2.47, star in middle of the "W" asterism.
This star is just outside of the frame. It's above upper Right corner, some glow from it can be seen in an image.
Since there is only Two hours of H-a, I'll shoot more lights for this in near future.
IC 63 in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
There was almost no emission in S-II channel.
Technical details:

Levels, curves and color combine in PS CS3.
Telescope, Meade LX200 GPS 12" @ f5
Camera, QHY9 Guiding, SXV-AO @ 8,5Hz
Image Scale, 0,75 arcseconds/pixel
Exposures H-alpha 6x1200s, binned 1x1
O-III 1x1200s, binned 3x3
S-II 2z1200s, binned 3x3
An experimental starless image to show the actual nebula
Looks like an open mouth man with a frozen nose...

NGC 2032 as an animated 3D
Animations are made by creating artificial parallax to an image. Then two images are animated together by using conversion web service, Start3D. There can be some artifacts in images, due the experimental nature of this work! The volumetric models are based on some known facts and an artistic impression.
Please, let the images load for few seconds to see them animated!

NGC 2032 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.
