A scale study of the Veil Nebula supernova remnant




I have shot many targets with several focal lengths. Due to that, I will publish some of my material as image sets, with a different field of view and level of details. The fractal nature of our universe stands out nicely in this way and it will make the orientation more easy.

Many times, it's difficult to understand the image scale of astronomical images.
Therefore I have added a "Moon circle" in the images to show the angular scale in the sky. The full Moon has an angular size of ~30 arc minutes, that's equal to ~0,5 degrees.


A new scale study, the Veil Nebula


Note. The apparent size of the Moon is marked as a white circle for a scale.


Images used in this series:

Two images at top are shot with the Canon EF 200mm f1.8 camera lens and QHY9 astronomical camera with the narrowband filters: 

Images at middle are shot with SkyWatcher 80 ED telescope at  ~700mm focal length:

Image at bottom is shot with Meade LX200 GPS 12" telescope at ~f5:
