Veil Nebula in O-III light

Veil Nebula with O-III filter only.
-
This is a start of the new project.
I will shoot The Veil Nebula in two color narrowband,
where O-III is Blue and H-alpha is Red, Green will be
synthesized from Red and Blue.
-
Not a very good star though, at fist night (29.09.) I was able to shot
only three 20min. frames. Thats a way too litle for O-III light.
I'll shoot more , if weather up here ever permits it,
two more hours is needed here, I think.
-
In the final image O-III will be precented as Blue color.
Tokina 300 AT-X @ f2.8, is a very good lens for this target,
the field of view is perfect march for the Veil.
_
Here is an image where stars are removed,
it's interesting to see how far the O-III area really goes.
