Sh2-142, the "Wizard Nebula", wide field & a closeup reprocessed
Since my processing technique gets better and weather doesn't give any support, I have reprocessed some older images. There is now star colors added and other processing is tweaked too.
Sh2-142, the "Wizard"
Ra 22h 47.0m Dec 58° 06′
Image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.
NGC 7380 is an open cluster inside the nebula. The "Wizard Nebula" is also known as a Sharpless catalog number 142. (Sh2-142) The nebula is relatively large object located in constellation Cepheus about 7000 light years away.
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.
Image is shot with a QHY8 and the Tokina AT 300mm f2.8 lens at full aperture.

This is a newer closeup image of the actual nebula. It covers about 30 arc minutes horizontally.

NOTE! This is a personal vision about forms and shapes, based on some known facts and an artistic impression.
The "Cone nebula" as an anaglyph Red/Cyan 3D
You'll need Red/Cyan Eyeglasses to be able to see this image right.
Note, if you have a Red and Blue filters, you can use them! Red goes to Left eye.

Two ways to end a life, A planetary nebula and a supernova remnant
Since my processing technique gets better and weather doesn't give any support, I have reprocessed some older images. There is now star colors added and other processing is tweaked too.
Sh2-221, 216, 217 and 219
in constellation Auriga
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.
Note. Looks like that there is an outer shell in the Sh2-216 planetary nebula at a right hand side of the image
It's visible only in ionized sulfur channel, I never seen it before in any image. It can be seen as a red color in HST-palette image above. It's most visible at twelve and six a clock position above and belove the main body of the nebula.
In this rare image, two Stars has ended they lifes. Right one is an old, very dim and large, Planetary Nebula and the Left one is an extremely dim Supernova remnant. The North is Up and the field of view is about 5,5 degrees horizontal.
I have seen very few images of eather of them, and never seen them as a three colour narrow band.
Objects in the image are from the Sharples Catalog. Left one is Sh2-221 and the Right one Sh2-216.
There are other smaler Sh2-objects too in a same field, Sh2-217 and Sh2-219, they are all located in constellation Auriga.
