Eta Carinae Nebula in narrowband

Imaged from Melbourne, Australia (15 km from CBD). 15 hours total.

CCDStack2 was used to calibrate, register, normalize, perform data rejection, and final stacking. Final combining of the data to false colour was performed in Photoshop 6.

The SII data was mapped to the red channel, Ha to green, and OIII mapped to the blue channel.

Image details:
12 X 25 min in SII 8nm
13 X 25 min in Ha 7 nm
13 X 25 min in OIII 8.5 nm

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
