Panorama from the Butterfly to Crescent

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.

Cygnus panorama

A panorama from the Butterfly to the Crescent Nebula in constellation Cygnus.
Image is in HST-palette from an emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Note. Size of the full Moon is marked as a gray circle, at lower Right corner, for a scale.

There are two individual images used to make this panoramic image:

  1. Butterfly Nebula,
  2. Crescent Nebula,

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.

There is a third overlapping image from the same area, the "Tulip Nebula". I have a panoramic image containing it as well. I like this panorama but it's so long, that image gets very small, so I didn't place it as a main image in this post.

A long and narrow version, with the "Tulip Nebula"

Tulip Nebula, the original image:

All images in this page have been part of an older mosaic, the "Cygnus Trio"
It was my very first APOD (Astronomy Picture Of  Day) published  by NASA.
