Description

Like a flaming canonball NGC 3293 appears to explode outwards from the eta carina nebula

Around 7 hours of integration taken over 3 nights (setting earlier these nights).

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.
