Rosette Nebula, the scale in a sky, zoom in series in natural colors
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.
"Rosette Nebula"
Ra 06h 33m 45s Dec +04° 59′ 54″, in constellation Orion
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.
1. Two panel mosaic of Cone and Rosette Nebulae. Shot with a Canon EF 200mm f1.8 lens, Baader NB-filters and QHY9 cooled astronomical camera.
2. The Rosette half of the mosaic image.
3. Rosette Nebula with a Tokina AT-X 300mm f2.8 lens, Baader NB-filter set and QHY9 astro camera.
4. Rosette closeup with Meade LX200 GPS 12" 2000mm, NB-filters and QHY9 camera.
