The Bubble Nebula in HST-palette
I relized yesterday, that I actually shot Narrowband colors for the Bubble Nebula!
The colors are from a small part of the wide field image belowe. I marked it there.
This image of Sh2-157 is shot November 10 2008. The original image and data can be found
The original Bubble nebula, from 2007, is Shot with much higher focal lenght. It can be found HERE.-

It's amazing how litle and low resolution color information is enough to build HST-palette image.
The signal from S-II and O-III channels is carefully mixed to a H-a channel.
Then the O-III and S-II boosted H-a channel is used as a luminance.
I must try this tecnique with some other, older , narrowband images as well!

Nebula images are taken with a UHC-filter or are H-a RGB-compositions,
so they are in natural colors.

You can compare how additional Five hours of H-a hellped by looking two previous versions.
First, there is only Two hours of H-a:
Really bad looking and noisy,
Secondly there was 11 hours of H-a, looks much better:
-
This is a really dim Supernova Remnant pair, with fast, f1.8, optics
it has taken 16h of H-alpha light to get in this version.
