Sharpless 157, Sh2-157, apparent scale in the sky
I have shot many targets with several focal lengths.
Due that, I will publish some images 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.
Sharpless 157
In constellation Cassiopeia
Note. Size of the full Moon is marked as a gray circle, at upper Right corner, for a scale.
Other targets in images above
The "Bubble Nebula" can be seen in upper Left corners.
The "Wizard Nebula" locates at utmost Right at the top panorama stripe.
There are two individual images used to make this image series
