Hi all
As usual the weather has turned to wet and cloudy and a bout of laryngitis means that I have been able to catch up with some processing and also to have a go at a bit of experimentation. A couple of weeks ago when I captured the Ha data for my Horsehead image I also managed to capture an hour each of Ha, OIII and SII in 10 minute unguided subframes for the Rosette nebula (NGC 2237-9,46) so first of all I did an image using the HST palette of SII for red, Ha for green and OIII for blue using the Ha data for the luminance layer as well. After I procesed it I thought I'd see what the results would be if I swapped the palette around a bit and I think I got slightly carried away. Any way the results are below in the following order
1. HST palette --- SII=R Ha=G OIII=B
2. Reverse HST palette --- OIII=R Ha=G SII=B
3. CFHT (Canada France Hawaii Telescope) palette --- Ha=R OIII=G SII=B
4. Unconventional palette (I used it before on the Crescent nebula) --- Ha=R OIII=G OIII=B
Hope you like them and thanks for looking
All the images used the same Ha data as a luminance channel and all 4 images were processed at the same time to ensure the same processing was used for each one. Details of equipment used can be found on my website http://www.imagingtheheavens.co.uk (http://www.imagingtheheavens.co.uk/)
