IC 1396, the scale in a sky, zoom in series


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.

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

    1. 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.  
    2. A IC1396 part of the mosaic, Canon FD 200mm f2.8.
    3. Target imaged with a Tokina AT-X 300mm f2.8 camera lens. 
    4. A close up of the "Elephant's Trunk Nebula" iumaged with a Meade LX200 GPS 12" telescope, focal lenght ~2000mm.

Pelican Nebula, IC 5070, The scale in a sky, zoom in series





I have shot many targets with several focal lengths. 
Due that, I will publish some older images as an image sets, with different field of view and detail levels.

A HST-palette closeup of the Pelican Nebula.
NOTE. The size of the full Moon (0,5 degrees) is marked as a scale.

Two images are used for the series, first is a wide field shot with a Tokina AT-X 300mm f2.8 camera lens.
Second image, at the bottom, is shot with a Meade LX200 GPS 12" reduced under 2000mm.
Baader narrowband filter set was used with both images, wide field was shot with a QHY8 and closeup with QHY9 cooled astronomical cameras.

IC410
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.

Three images are used for the 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
1. First wide field shot:

IC405

EDIT.
I found an older image of IC 405 & 410 from my HD, it's shot back in Winter 2008. I added it as a part of zoom in series.

The full Moon





Sharpless 101, the "Tulip Nebula"
In constellation Cygnus



Images are in HST-palette, (HST=Hubble Space Telescope) from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen. Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.
NOTE. The size of the full Moon (0,5 degrees) is marked as a gray circle in all of the images.


First image is a three panel mosaic of the "Cygnus Trio"
Second one is two panels from a mosaic.
The mosaic wide field was shot with a Tokina AT-X 300mm f2.8 camera lens.
A closeup image, at the bottom, is shot with a Meade LX200 GPS 12" reduced under 2000mm.
Baader narrowband filter set was used with both images, wide field was shot with a QHY8 and closeup with QHY9 cooled astronomical cameras.
