IC 405, apparent scale in a sky in two palettes, redone




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. 


IC405, the "Flaming Star Nebula"
An emission Nebula in constellation Auriga

Images are in HST-palette from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
NOTE. The size of the full Moon (0,5 degrees) is marked as scale.


Images are in Natural color palette from the emission of ionized elements, R=Hydrogen + Sulfur, G=Oxygen and B=Oxygen + Hydrogen.
NOTE. The size of the full Moon (0,5 degrees) is marked as scale.

Three images are used for the both series.  
First is a wide field shot with a Canon FD 200mm f2.8 camera lens.
Second image, is imaged with a Tokina AT-X 300mm f2.8.
Third image is done with a Meade LX200 GPS 12" reduced little under 2000mm.
Baader narrowband filter set was used with all images, wide field images was shot with a QHY8 and closeup with QHY9, both are cooled astronomical cameras.


Original images with technical details

NGC 4565
An edge on galaxy in constellation Coma Berenicest

A broad band RGB-image of NGC 4565

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.
