Messier 76, the "Little Dumbbell Nebula", apparent scale in the sky





I have shot many targets with several focal lengths. 
Due that, I will publish some of my material as an image sets, with different field of view and detail levels.
The fractal nature of our universe stands out nicely by this way and it will make the orientation more easy.

Many times, it's difficult to understand the image scale of astronomical images.
Due that, I will add a Moon circle in some of the images to show the angular scale in a sky. 
The full Moon has an angular size of ~30 arc minutes, that's equal to ~0,5 degrees.



M76, the "Little Dumbbell Nebula"
In constellation Perseus.

NOTE. The size of the full Moon (0,5 degrees) is marked as a gray circle in all of the images.
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.

One image of M76 is used to make this image series,

Ra 19h 59m 36.340s Dec +22° 43′ 16.09″



NOTE. The size of the full Moon (0,5 degrees) is marked as a gray circle in all of the images.
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. Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.This composition is very close to a visual spectrum.

Deep deep space, an anaglyph Red/Cyan 3D movie




NOTE!
You'll need Red/Cyan Eyeglasses to be able to see the movie as 3D.
If you have a Red and Blue filters, you can use them! Red goes to Left eye.



A ten minute still motion movie from a collection of my experimental 3D-astronomical objects.




Please note, there is a HD-selector, at lower Right corner of the window, set to 360p.
If you like to see the movie in higher resolution, use this selector. Maximum resolution of the movie is 1080p.
Double click the movie window to see it in full screen!

3D-images used in the movie and more can be found, in different 3D-formats, from my portfolio.

All the material in this movie have been imaged and converted by me. Original 2D-images used for the movie, can be found here: http://astroanarchy.zenfolio.com/

IC1848, the "Soul Nebula", apparent scale in the sky

IC 1848 zoom in
In constellation Cassiopeia




Image is in HST-palette from the emission of ionized elements, R=Sulfur,
 G=Hydrogen and B=Oxygen. NOTE. The size of the full Moon (0,5 degrees) is marked as a gray circle in all of the images.


IC 1848, second zoom in


NOTE. The size of the full Moon (0,5 degrees) is marked as a gray circle in all of the images.
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. Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.This composition is very close to a visual spectrum.


Images used in the series above from top to bottom



  1. A wide field image of the area, covering about 5 degrees, ~300', of the sky. (Ten full Moons side by side)
    IC 1805, the "Heart Nebula", locates at upper Right and  IC 1848 can be seen at lower Left. Image is shot with a Canon EF 200mm f1.8 camera lens and a QHY9, a cooled astronomical camera.
    Baader narrowband filter set, total exposure time was ~1,5 hours (A very fast lens was used!).
  2. A medium wide field image is shot with a Tokina AT-X 300mm f2.8 camera lens and a QHY9, a cooled astronomical camera. Baader narrowband filter set, total exposure time was ~5 hours .
  3. Last image was shot with a Meade LX200 GPS 12" telescope @ f0.5 and a QHY9, a cooled astronomical camera.Baader narrowband filter set, total exposure time was ~2,5 hours.
