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,

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/

A panorama from the Sharpless 221 to 216




While making scale studies from various objects, I did make some new panoramas from archived images.
I will publish some of them as an individual images, comments and suggestions are welcome.


Sharpless panorama, Sh2-216, 217, 219, 221 and BFS44 
East of constellation Camelopardalis


Image is in HST-palette from an emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.


There are two individual images used to make this panoramic view:



  1. Left side, http://astroanarchy.blogspot.com/2011/01/two-ways-to-end-life-planetary-nebula.html
  2. Right side, http://astroanarchy.blogspot.com/2011/02/sh2-216-project-finalized.html

This image covers over six degrees of sky horizontally, that's 12 full Moons side by side. Here is a "scale study out of this target, the Moon is marked as a gray circle:

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.
Note. Size of the full Moon is marked as a gray circle, at lower Right corner, for a scale.


An annotated image shows objects in the field


There are very little information out of objects in the image and there is very few images from them generally.
I think, this must be the first three band narrowband image out of this field.

Objects in this image are spread out over wide range of distances. They are not forming a single complex, like the Cassiopeia arc west of Camelopardalis. The largest objects in a field are Sharpless 221 and 216.

First from the Left is a supernova remnant, SNR 160.4+02.8 (Sh 2-221) , the distance is unknown. 
The Planetary Nebula,  PK 158+00 1 (Sh 2-216) , at Right end of an image, distance of only 120 parsecs (~390 light years) makes this to a one of the oldes and largest planetary nebula known.

Smaller objects in a field are Sh2-217, 4100 solar mass molecular cloud at distance of 5200 parsecs (0ver 16.000 light years) and Sh2-219, an HII region at distance of 4200 parsecs (Over 13.000 light years)
Last object BFS44, at bottom center, located at distance of 6100 parsecs (over 19.000 light years), almost nothing has been published from this object.

Panorama from the Butterfly to Crescent





While making scale studies from various objects, I did make some new panoramas from archived images.
I will publish some of them as an individual images, comments and suggestions are welcome.


Cygnus panorama

A panorama from the Butterfly to the Crescent Nebula in constellation Cygnus.
Image is in HST-palette from an emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Note. Size of the full Moon is marked as a gray circle, at lower Right corner, for a scale.

There are two individual images used to make this panoramic image:

  1. Butterfly Nebula, http://astroanarchy.blogspot.com/2011/01/butterfly-nebula-reprocessed.html
  2. Crescent Nebula, http://astroanarchy.blogspot.com/2011/01/ngc-6888-crescent-nebula-wide-field.html

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.


There is a third overlapping image from the same area, the "Tulip Nebula". I have a panoramic image containing it as well. I like this panorama but it's so long, that image gets very small, so I didn't place it as a main image in this post.

A long and narrow version, with the "Tulip Nebula"

M57, the "Ring 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.


M57, A planetary Nebula
In constellation Lyra

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.

This is generally a difficult target, due the small angular size and an extreme dim outer ring structure versus bright core. 

One image of M57 is used to make this image series.
