A panorama mosaic from the IC1396 to Sharpless 129
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 IC 1396, the "Elephant's Trunk Nebula" to the Sh2-129
In constellation Cepheus
There are two individual images used to make this panoramic image:
- IC 1396, http://astroanarchy.blogspot.com/2011/01/ic-1396-reprocessed.html
- Sharpless 129, http://astroanarchy.blogspot.com/2008/03/sh2-129.html
- some data from newer image of Sh2-129, http://astroanarchy.blogspot.com/2011/01/sh2-129-reprocessed.html

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

A panorama from the Sharpless 221 to 216
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.
Sharpless panorama, Sh2-216, 217, 219, 221 and BFS44
East of constellation Camelopardalis
Image is in HST-palette from an emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
There are two individual images used to make this panoramic view:
- Left side, http://astroanarchy.blogspot.com/2011/01/two-ways-to-end-life-planetary-nebula.html
- Right side, http://astroanarchy.blogspot.com/2011/02/sh2-216-project-finalized.html
This image covers over six degrees of sky horizontally, that's 12 full Moons side by side. Here is a "scale study out of this target, the Moon is marked as a gray circle:
Note. Size of the full Moon is marked as a gray circle, at lower Right corner, for a scale.
An annotated image shows objects in the field
There are very little information out of objects in the image and there is very few images from them generally.
I think, this must be the first three band narrowband image out of this field.
Objects in this image are spread out over wide range of distances. They are not forming a single complex, like the Cassiopeia arc west of Camelopardalis. The largest objects in a field are Sharpless 221 and 216.
The Planetary Nebula, PK 158+00 1 (Sh 2-216) , at Right end of an image, distance of only 120 parsecs (~390 light years) makes this to a one of the oldes and largest planetary nebula known.
Smaller objects in a field are Sh2-217, 4100 solar mass molecular cloud at distance of 5200 parsecs (0ver 16.000 light years) and Sh2-219, an HII region at distance of 4200 parsecs (Over 13.000 light years)
Last object BFS44, at bottom center, located at distance of 6100 parsecs (over 19.000 light years), almost nothing has been published from this object.

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
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:
- Butterfly Nebula, http://astroanarchy.blogspot.com/2011/01/butterfly-nebula-reprocessed.html
- Crescent Nebula, http://astroanarchy.blogspot.com/2011/01/ngc-6888-crescent-nebula-wide-field.html
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"

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.
