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.
The full Moon
IC1396 and the "Elephant's Trunk Nebula"
In constellation Cepheus
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.
Images used in the series above from top to bottom
- A wide field mosaic of IC1396 and Sharpless 129, Sh2-129, at Left. Image is taken with a Canon FD 200mm f2.8 camera lens.
- A IC1396 part of the mosaic, Canon FD 200mm f2.8.
- Target imaged with a Tokina AT-X 300mm f2.8 camera lens.
- A close up of the "Elephant's Trunk Nebula" iumaged with a Meade LX200 GPS 12" telescope, focal lenght ~2000mm.
