IC1848, the "Soul Nebula", apparent scale in the sky
I have shot many targets with several focal lengths.
Due that, I will publish some of my material as an image sets, with different field of view and detail levels.
The fractal nature of our universe stands out nicely by this way and it will make the orientation more easy.
Many times, it's difficult to understand the image scale of astronomical images.
Due that, I will add a Moon circle in some of the images to show the angular scale in a sky.
The full Moon has an angular size of ~30 arc minutes, that's equal to ~0,5 degrees.
IC 1848 zoom in
In constellation Cassiopeia
Image is in HST-palette from the emission of ionized elements, R=Sulfur,
G=Hydrogen and B=Oxygen. NOTE. The size of the full Moon (0,5 degrees) is marked as a gray circle in all of the images.
IC 1848, second zoom in
NOTE. The size of the full Moon (0,5 degrees) is marked as a gray circle in all of the images.
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.
Images used in the series above from top to bottom
- A wide field image of the area, covering about 5 degrees, ~300', of the sky. (Ten full Moons side by side)IC 1805, the "Heart Nebula", locates at upper Right and IC 1848 can be seen at lower Left. Image is shot with a Canon EF 200mm f1.8 camera lens and a QHY9, a cooled astronomical camera.Baader narrowband filter set, total exposure time was ~1,5 hours (A very fast lens was used!).
- A medium wide field image is shot with a Tokina AT-X 300mm f2.8 camera lens and a QHY9, a cooled astronomical camera. Baader narrowband filter set, total exposure time was ~5 hours .
- Last image was shot with a Meade LX200 GPS 12" telescope @ f0.5 and a QHY9, a cooled astronomical camera.Baader narrowband filter set, total exposure time was ~2,5 hours.
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.

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.

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.
