NGC7380, the "Wizard 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.


NGC 7380, Sharpless 142 (Sh2-142)
In connstellation Cepheus


Sh2-142 alias NGC 7380, 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.

  2. A Sh2-142, the Wizard Nebula part of the mosaic, Tokina AT-X 300mm 
  3. Zoomed in version from the previous image 
  4. A close up of the Nebula imaged with a Meade LX200 GPS 12" telescope, focal lenght ~2000mm.A zoomed
