The Bubble Nebula in HST-palette
![](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjtRcwPwrSq1veox5LK_OUI984_1y4WFiSukHGYFtJYxpeEX_nnLzZLvnvpvKBLuebdr6zPfOCrdADeXa3wwHFKc9-Zjaed-VLYqNyD6R16-_R8VCeFL-nKUcHH_dO3UaW9MKv8sKyAb_U/s400/Bubble_HST.jpg)
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.

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.

shot them.

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.
