Eta Carina Nebula, a less imaged part

Hi All,

This image is part of a series I'm doing, of the nebulae around Eta Carina. Some of the nebulae are really quite beautiful and not imaged much in high resolution. You get glimpses of the nebulae in wide field images of the area, but mostly they are ignored in favour of the more famous central part of the nebula.

Anyway, I hope you like it. Narrowband image, mapped in HST palette, tweaked in my usual fashion. This is the first pass, I may change the colours.

I would appreciate some feedback re the amount of sharpening used, the halos around the stars aren't from sharpening the stars, but come from the increase in brightness of the nebula around the stars with the stars deselected during the sharpening process. I really went to town on the sharpening and may have overdone it, but I love the detail it brings out.

Two full nights imaging, about 7 hours Ha, 3 each of SII and OIII. ASA N12 scope on PMX, STT8300 camera.

Larger version here.

Share and Enjoy.

Cheers
Stuart
