A set of wide fields vs closeups





Since the weather doesn't support shooting any new material, I have done more image pairs from same target.
I have shot many targets with least two different focal lengths, usually a 200-300mm camera lens and my old Meade LX200 GPS 12" telescope. I have done earlier some scale studies as a zoom in series, with Moon circle as a scale.
Now I have done just simple image pairs, showing both, a wide field and a closeup from the same objects.



Sh2-142, the "Wizard Nebula"

Ra 22h 47m 0s Dec +58° 06′ 00″, in constellation Cepheus



Image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.



Links to the original images, used in series, from top to bottom, 300mm vs  ~2000mm






NGC 7000, the "North America Nebula"

In constellation Cygnus



Image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.

IC443, the "Jellyfish Nebula"

In constellation Gemini



Image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
