Panoramic mosaic from the M52 & Bubble to Wizard Nebula
While making scale studies from various objects, I did make some new panoramas from archived images.
I will publish some of them as an individual images, comments and suggestions are welcome.
Panorama, from M52, Bubble Nebula & Sh2-157 to the Wizard Nebula
In constellation Cassiopeia
A panorama from the M52 to the Wizard Nebula in constellation Cassiopeia.
Image is in HST-palette from an emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
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. Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.This composition is very close to a visual spectrum.
Note. Size of the full Moon is marked as a gray circle, at lower Left corner, for a scale.
There are two individual images used to make this panoramic image:
- Sharpless 157, http://astroanarchy.blogspot.com/2011/03/sh2-157-reprocessed.html
- Wizard Nebula, http://astroanarchy.blogspot.com/2011/02/sh2-142-wizard-nebula-wide-field.html
