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.
NGC 2264, the "Cone Nebula"
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.
HST-palette version of the zoom in series above:
Images used in the series above from top to bottom
- 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.
- The Cone Nebula half of the mosaic image.
- Zoomed in version from the previous image
- A close up of the Cone Nebula imaged with a Meade LX200 GPS 12" telescope, focal lenght ~2000mm.
