The "Bug Nebula", NGC6302 as an animation








The animation is made by splitting the original 2D-image to a layers by the image content. Layers are then taken to a 3D-modeling software, "TrueSpace", and projected to a 3D-surfaces and animated to a movie file.
Stars are placed to Z-axel by apparent brightness , brighter ones are closer.

Original images and imaging details can be found here:

Images from the NG members remote Australian telescope, 06.05 - 21.07.2010



Here is a small slideshow about all the images taken with the Northern Galactic members remote telescope, 16"RCOS, in Australia between 06.05 and 21.07.2010
Image of the instrumentation can be seen HERE.





All my astronomical images, normal and some experimental 3D work, can be found from my portfolio:

IC 5150, a Planetary Nebula




IC 5150, a Planetary Nebula in constellation Grus.

This rarely imaged southern planetary is dimmish, magnitude about 12. Due the full Moon, it's imaged with narrow band filters. Only H-a and O-III are used to compose the natural bi-color version.
This object will be better imaged with a broad band LRGB, since it emits some strongish continuous spectrum but as mentioned, the full Moon prevent me to do so.
I haven't seen any narrow band color images of this earlier! 


The telescope and technical information:

16" RCOS ja Apogee U9000 camera. 
LRGB combo.
H-alpha 3x1200s, Dark and artificial Flat calibrated.
O-III 3x1200s, Dark and artificial Flat calibrated.
Raw data is shared with "Team Finland"

Processing workflow:
Image acquisition, MaxiDL v4.xxx
Stacked and calibrated in CCDStack.
Levels, curves and color combine in PS CS3.

NGC 6302, the "Bug 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.

NGC 6302, the "Bug Nebula", (also called the "Butterfly Nebula") is a bipolar planetary nebula in the constellation Scorpius. The central star is one of the hottest of its kind, about 200.000 K. The central star can't be seen due the dense equatorial disc composed of gas and dust. The disc might be the reason for the bipolar structure of this bright planetary nebula  Distance is about 3500 light years.
