Sh2-155, the "Cave 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.
Sh2-155, the "Cave Nebula" as a wide field image
Ra 22h 57m 17.14s Dec +62° 28′ 33.4"
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.
The Cave Nebula, Sh2-155 or Caldwell 9 is a very diffuse nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus.
The reflection, wide band, component can't be seen in my image, since this is a narrowband one.
Distance is about 2400 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.
Image is shot with a QHY8 and the Tokina AT 300mm f2.8 lens at full aperture.

The "Elephant's Trunk Nebula", inside IC 1396, 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.
IC 1396 and the "Elephant's Trunk Nebula"
In constellation Cepheus
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.
The elephant's Trunk nebula is a concentration of interstellar gas and dust in the star cluster IC 1396.
This ionized gas region locates in the constellation Cepheus about 2400 light years away.
Formation is coursed by a stellar wind, radiation pressure, from a group of massive young stars.
This image shows the location in large context
Image area is about three degrees wide. (Six full Moons side by side)
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.
Original versions from October 2009, with technical details:
Real RGB-colors with a H-alpha luminance boost. RGB-colors are shot at 2008 with a QHY8 color camera and the UHC-s filter.

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.
