Great Balls of Fire! NGC3324 [fixed] in SHO

After the previous 3 months of some of the most appalling always cloudy weather, the last month I have been literally gorging on clear skies and with narrowband filters even the moon can not dampen my spirits.

Like a flaming canonball NGC 3324 [fixed - thanks chris] appears to explode outwards from the eta carina nebula

High Res on Astrobin https://astrob.in/zyws09/0/

I've reverted to the straight TS flat here on the APM130 at 780mm FL.

Around 7 hours of integration taken over 3 nights (Carina setting earlier these nights). Could image a bit longer each evening, but I've been using the other 2/3 of the nights on a Prawn Project...hoping to get it well cooked in a day or two. Losing a few more subs than I'd like as guiding a bit more challenging at 780mm compared to 585mm.

Stacked and combined in APP mapping Ha, OIII, and SII in SHO and adding both OIII and SII as 80% green.

Then separately processed and combined the Ha OIII and SII layers in startools also in SHO.

To get more natural star colours (APP) I aligned the results from APP and Startools in PS and adjusted opacity till I got a compromise I liked. Final process to taste in PS using astronomy tools plug ins and selective colour mask adjustments.

Great image, but it's NGC3324. NGC3293 is the nice cluster just a bit to the right of your image.

Have just spent an hour trying to figure out how NGC3324 came by the name Gabriela Mistral Nebula.
Still no clue, but Lucila Godoy Alcayaga (her real name) won a Nobel prize in literature.
Maybe she wrote a poem about the stars?

Nice work Rob
