A small set of image pairs, Wide field vs closeup
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.
IC1396 and the "Elephant's Trunk Nebula"
In constellation Cepheus
Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission.

IC 1848, the "Soul Nebula"
In constellation Cassiopeia
Image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
