Zoom in series to Sharpless 234, 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.

An emission Nebula in constellation Auriga

Image is in HST-palette from the emission of ionized elements, R=Sulfur,

G=Hydrogen and B=Oxygen.
