An edge on galaxy, NGC4565, apparent scale in a 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.

I don't have too many galaxy images around, since I'm shooting from under a heavy light pollution .

Two images are used for the series above
  1. A gray scale image with a Canon EF 200mm f1.8@1.8 camera lens and the QHY9 cooled gray scale astronomical camera.
  2. A color image with a Meade LX200 GPS 12" and QHY8 cooled single shot color camera.
