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.

NOTE! This 3D-study is a personal vision about forms and shapes, based on some known facts and an artistic impression.

NGC 2032
NGC 2032 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.
NGC 2032, the "Seagull Nebula" (Don't mix to the IC 2177 at Northern hemisphere, also called "Seagull Nebula") NGC 2032 locates in Large Magellanic cloud and it's in boundary to supershell LMC4. The gas is in various complex forms due the strong solar wind, radiation pressure, from massive stars in the nebula.
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:
16" RCOS ja Apogee U9000 camera.
An Australian remote telescope
4x600s for the Luminance
3x1200s H-alpha
2x1200s O-III
2x1200s S-II
Dark, Bias and Flat calibrated.
Raw data is shared by Petri Kehusmaa and J-P Metsavainio
Processing workflow:
Image acquisition, MaxiDL v4.xxx
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations, added at 50% weight.
Levels, curves and color combine in PS CS3.
An experimental starless version.

Tucanae 47, a Globular cluster, reprocessed
LRGB image of Tucanae, NGC 104, globular cluster in constellation Tucana.16700 light years away from Earth and 120 light years across. Image field is about 30' x 30', half a degrees.
I did reprocessed this image, since at the time I didn't have good and functional calibration files.
RCOS ja Apogee U9000 camera.
LRGB combo.
Luminance 12x300s and 8x150s, Dark and Flat calibrated.
Red 5x300s, Dark calibrated
Green 5x300s, Dark calibrated
Blue 5x300s, Dark calibrated
Raw data is shared with Petri Kehusmaa and J-P Metsavainio
Processing workflow:
Image acquisition, MaxiDL v4.xxx
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 10 iterations
Levels, curves and color combine in PS CS3.
