A zoom in series of the Cave Nebula, Sh2-155
Now and then I have published some zoom in series of various objects imaged by me.
The purpose is to show the apparent scale in the sky. Beside that, this series shows nicely the fractal nature of our universe. Series are possible to make, since I have shot many objects with various focal lengths.
Like this one is shot with 200mm, 300mm and ~2000mm focal lengths
The Cave Nebula, a study about the scale in the sky
Note. A circle, size of the Moon, in the images as a scale. (An apparent scale of the Moon is 0,5 degrees, or 30 arc minutes.)

All images are in Mapped colors from the emission of ionized elements,
R=Sulfur, G=Hydrogen and B=Oxygen.
