California Nebula, NGC 1499, scale in a sky, zoom in series
I have shot many targets with several focal lengths.
Due that, I will publish some older 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.
The full Moon
California Nebula, NGC 1499
In constellation Perseus
NOTE. The size of the full Moon (0,5 degrees) is marked as a gray circle in all of the images.
