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.
I posted a slideshow about my astroimages from this season, 2008-09, ealier, it can be seen here:

There was 15 x 1200s from 03.11.2008, I totally frogotten, that I had
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.
Details; -Camera, QHY9 - Optics, Canon EF 200mm f1.8 @ 1.8 - Guiding, QHY5 and PHD-guiding - Platform, LX200 GPS 12" - Exposures, 7x1200s with 7nm H-alpha filter and 13x2400s, 5x300s O-III Binned 4x4 and 5x300s. S-IIBinned 4x4 .
Additional 15x1200s of H-a added, imaged with QHY8 and Tokina AT 300mm f2.8 @2.8
Darks, Flats and Bias frames calibrated. Total exposure time for H-alpha line is 16h!
