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 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.

3D-NOTE!


You'll need Red/Cyan Eyeglasses to be able to see images as 3D.
If you have a Red and Blue filters, you can use them! Red goes to Left eye.

All the original 2D-images are imaged by me.
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. 
Shapes are based on some known facts and an artistic impression.

IC 410, a "cosmic fertilization", 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.

from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.

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.

artist|rising portfolio




I have opened a small test gallery in artist|rising web service as a test.
There are some high resolution images for sale as a high quality printed copies 
They have a very good framing service as well.

A 3 day old Moon & Earth shine, one of the images in artist|rising portfolio

Sample pricing for archival photographic paper:
from 8x10" and 15,90$
up to 36"x48" and 59,99$

Sample pricing for heavy acid free watercolor paper:
from 8x10" and 19,90$

NOTE. I have a much large collection of images in my portfolio.

http://astroanarchy.zenfolio.com/
You can place an order for any image in the folder "My Best Images"
Price level is about the same as in artist|aising service above.
There is not as good options for a framing, hence this test with the artist|rising.

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. 


IC405, the "Flaming Star Nebula"
An emission Nebula in constellation Auriga

Images are 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 scale.


Images are in Natural color palette from the emission of ionized elements, R=Hydrogen + Sulfur, G=Oxygen and B=Oxygen + Hydrogen.
NOTE. The size of the full Moon (0,5 degrees) is marked as scale.

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.
