Anaglyph 3D from two targets, the "Tarantula" & the "Wizard"
The "Tarantula Nebula"
You'll need Red/Cyan Eyeglasses to be able to see this image right.

A grande finale of the Cepheus project, mosaic of ten panels with colors
I have planned this Cepheus project for a long time. Finally I have been able to finalize it. I have done some large mosaic images of nebula rich areas in our Milky way. The ultra fast camera optics, Canon EF 200mm f1.8, it's a perfect tool for the job. It has a large, flat and sharp, image field and full open at f1.8, it collects photons very fast. The final image covers an area of about 18x10 degrees. (Full Moon has an apparent size about 0,5 degrees. 720 full Moons are needed to cover this area in the sky.)
To have a color image, each of the panels have been shot three times. This narrowband image is shot with QHY9 (a cooled astronomical camera), Canon EF 200mm f1.8 camera optics full open, Baader Planetarium Narrowband filter set for an emission of ionized elements, Hydrogen, Oxygen and Sulfur. (H-alpha, O-III and S-III) The dimensions of the final mosaic image are 12000 x 6500 pixels.

An orientation in constellation Cepheus. The mosaic image covers an area of ~18x10 dgrees.
Technical details
I have used lots of an older material for this image. I have shot this area for years, with a different instruments, with different focal lengths and apertures. The total exposure time for the final mosaic image is calculated by adding the exposures for the actual mosaic to the exposures for sub-images used.

Sh2-142, the "Wizard Nebula"
Sh2-142 alias NGC 7380, in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
I use a starless image in one of the processing steps. Sometimes I publish it, since the actual nebula can be better seen by this way.
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.
NGC 7380 is a catalog number of the open star cluster inside Wizard nebula, SH2-142.
Nebula locates in constellation Cepheus, about 7000 light years from my home.

It looks like.... a collection of my photos as I see them
We have had a solid cloud cover, up here 65N, over two months now. My new imaging system stands useless at the rooftop, very frustrating.
We are easily seeing quasi logical forms in random shapes since we have a most powerful shape recognition machine in our brains. Based on previous phenomena, I made a funny collection out of my photos. There is an original version of my photo and same photo as I see it in my head. Part of the images are named after my own observations and some are commonly known nicknames. NOTE. All of the astronomical photos in this blog post are originally taken by me.
