This image was taken under the glorious light dome of Melbourne. Just 15 km from the CBD of Melbourne. I know the framing can be better. But this image started out as a test image, where I was testing my equipment, measuring and recording stuff. Well in the end, I just kept adding to it. I have seven nights here where I would set up. Polar align, and tear down each each night I imaged. It is presented at half resolution of the original, full frame, not cropped.

Data:
Vixen R200SS with comma corrector (f4 8 inch newt)
Astro-Physics AP900 mount.
SBIG 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

Image Processing:

CCDStack was used to calibrate, align, normalise, data rejection, and finally
perform the stacking for each channel.
ImagesPlus was used for texture enhancement and additional stretching
PhotoShop was used to combine the data into a false colour Hubble Palette image.

There is probably about 60 min work into the image processing. I am sure, if I
knew more in this area, there should be enough data to make a great shot.
