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






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.

Horse Head Nebula, an annoying preview






Horse Head Nebula, Barnad 33 and IC 434, is a dark nebula in constellation Orion. Image is taken from "down under". In Australia this nebula has a higher elevation, than here at 65N. 

Why annoying?

This image is a composition of 3 x 1200s H-alpha light. With this modest exposure time, image is far better, than I have managed ever taken up here with a longer integration time, that's annoying!


A false color H-alpha

We will shoot more data for this object in near future. LRGB and more H-a, maybe some O-III and S-II to see, if there is any.

16" RCOS ja Apogee U9000 camera.

M57, the "Ring Nebula", project finalized







A narrow band and broad band luminance mix image of the M57 as a bi color, H-alpha & O-III, composition.Not too commonly imaged outer halo structure can be seen in an image. There is least two layers of it, outer one is faintly seen in this image. A clear O-III signal is visible in a first layer of outer halo.
The halo was clear in H-alpha channel and there was some hints of it in luminance one.

Ring Nebula, M57, NGC 6822, locates in constellation Lyra, near a very bright star Vega. This planetary nebula lays about 2300 light years away from the Earth and has a diameter of 1,3 light years.
The small angular diameter, 230" x 230", makes this target difficult to image. The central white dwarf of planetary nebula nucleus is seen in an image as a Bluish dim star, visual magnitude is 15,75. Star was visible only in O-III channel and luminance channel.

3D-study of NGC 300 galaxy



An experiment with the NGC 300. All the stars from our milky way are removed and the original 2D-galaxy image is the projected to a 3D-surface. The resulting 3D-model is animated to a movie file. The purpose is to show the actual shape of the galaxy, now distorted by a perspective.


Original 2D-image and the technical data:








NGC 300







NGC 300, the spiral galaxy in constellation Sculptor, distance is about 6 million light years.

 It's likely, that NGC300 and NGC55 forms a gravitationally bound pair.
I have shot NGC 55, an irregular galaxy, ealier and it can be found here:
http://astroanarchy.blogspot.com/2010/09/ngc-55-irregular-galaxy-in.html

Image of NGC 55
"NGC300 and NGC55 forms a gravitationally bound pair."

Surface brightness is lowish and this image gave me a hard time when processing the raw data. I tried to keep a "diffused" look of it. Active parts of this galaxy can be seen as a Blue and Red areas in a spiral arms.

Something extra in my image

A bright trail trough a single raw frame of NGC 300.

A closeup, there is odd looking pattern inside of trail.


Mystery was solved by a help from Bert Candusio, the administrator of Northern Galactic group.
Object seen in the image is a geocentric satellite COSMOS 1536.
Thank you Bert.
