The data for this image was very kindly provided by Terry Robison from Australia, this object isn't visible from the UK so it was nice to be able to play with some data from another part of the world. Exposure and equipment details are as follows
Location:
Melbourne Australia. (15 km from CBD)

Gear:
Vixen R200SS with comma corrector (f4 8 inch newt) – stock focuser
Astro-Physics AP900 mount.
First generation ST-8300 mono running at -15C
Baader Narrowband Filters: SII 8nm, H-alpha 7 nm, and OIII 8.5nm

Exposure times:
SII 17 x 20 min mapped to Red
Ha 18 x 20 min mapped to Green
OIII 16 x 20 min mapped to Blue

The processing that I did to the three Fit files were as follows
Processing
Stretched in Maxim DL using gamma stretch with value of 0.1 at maximum pixel value and 16 bit, then saved to 16 bit tiff with a linear screen stretch
Equalise histograms in CS5 then colour combine to HST palette
combination of levels and curves with some minor contrast curves adjustments
