NOTE! This is a personal vision about forms and shapes, based on some known facts and an artistic impression.
Veil 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.

Cone and Rosette Nebulae 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.
Cone & Rosette Nebulae
A two panel mosaic
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.
Both nebulae are located in constellation Orion.
Images are taken with a Canon EF 200mm f1.8 lens, at full aperture, with Baader NB filter set and the QHY9 camera.

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.

A supernova remnant, the "Veil Nebula" 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.
Veil Nebula
Ra 20h 45m 38.0s Dec +30° 42′ 30″
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.
optically it has lowish surface brightness.

An older image from 2007 of Eastern part of the nebula, NGC 6995. Sky Watcher 80 ED with an UHC-s filter and QHY8. Exposure time about 4h.
Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.
Original versions from Autumn 2008, with technical details:
I have made an experimental movie about the structure of the nebula. It can be found here:
