NGC 281, The "Pac-Man Nebula", reprocessed
Since my processing technique gets better and the time of year doesn't give any support, I have reprocessed some older images. There is now star colors added and other processing is tweaked too.
NGC 281, in Cassiopeia
Ra 00h 52m 59.3s Dec +56° 37′ 19″
HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
NGC 281 is an H II region in the constellation of Cassiopeia. It includes the open cluster IC 1590 and several Bok globules (dark doo-dads at center of the Blue area). NGC 281 is also known as thePacman Nebula for its resemblance to the video game character from early 80's.NGC281 spans over 80 light years at its estimated distance of 9500 light years.
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. This composition is very close to a visual spectrum.

Due the huge distances, no real parallax can be imaged to form a volumetric information.
I have developed a method to turn any 2D-astronomical image to a various 3D-formats.

Emission nebula IC 410 and an open cluster, NGC1893, inside it are located in constellation Auriga about 12.000 light years from my home town Oulu in Finland. The cloud of glowing gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893.
"Cosmic tadpoles" are potentially sites of ongoing star formation, they are about 10 light-years long.
Emission from sulfur atoms is shown in red, hydrogen atoms in green, and oxygen in blue hues in this false-color, narrow band composite image above.
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. This composition is very close to a visual spectrum.

IC 405, apparent scale in a sky in two palettes, redone
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.

Three images are used for the both series.
First is a wide field shot with a Canon FD 200mm f2.8 camera lens.
Second image, is imaged with a Tokina AT-X 300mm f2.8.
Third image is done with a Meade LX200 GPS 12" reduced little under 2000mm.
Baader narrowband filter set was used with all images, wide field images was shot with a QHY8 and closeup with QHY9, both are cooled astronomical cameras.
