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.
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.
In constellation Cygnus
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.
