NGC1499, the "California Nebula" as a Stereo pair
This target reveals new structures in emission line imaging.
I made this presentation to show, how to I see, the structure
of this beautiful nebula.
-
Triple ionized Oxygen (O-III) signal was weak,
it can be seen as a Blue in the image. It seems to reach up to bright
star "Menkib" (HIP18614).
Menkib is energizing the strong emission from NGC1499,
outburs of O-III looks like relating to it.
Very interesting, but I don't know is this well known phenomen.

As usual, there is two versions. One for parallel vision, and the other one for cross vision methods. Thats because some part of the viewers can see one of the method in 3D, but not the other. (I can't see cross vision images - How to see this in 3D? Please, look for the right hand side menu for instructions.
Klick this image, if you can't see either of the stereo methods above. This is a animated image showing steroimage as a small animation. It will gives an idea, what can be seen in stereo images.

Sh2-157
My Sharpless Catalog project continue with Sh2-157.
Sh2-157 is a faint large nebula. Famous Bubble Nebula can be seen in upper left corner.This nebula looks like a gigant termite head to me.
Three versions precented here, first is in a Hubble palette,
second in "natural" colors and
third is an image with reduced stars to better show nebulosity, there seems to be lots offaint double ionized Sulfur (S-II) around.

IC405 & IC410
It's nice to make a black and white image
after so colorfull shots.
In the image there is two main objects, IC410 and IC405, sometimes
called as a "Flaming Star Nebula".
IC405 is a emission nebula but it has reflecting nebulosity too.
In my heavily lightpolluted location it's not easy to capture.
Trough Hydrogen alpha filter just emission part is captured.

Editted 9.11.
Ok. I can't live without colors, let's face it,
so I added this false color Ha-composition here.
Red = Starless Ha 100% R = 0% B = 17% Ha (Works as a H-beta substitute)
