SPX350 F4.5, ATK16HR, Astrodon Ha5nm OIII 3nm.

Just a quickie, I left this one too late and moving behind the roof I had to set up quickly and did not have time to collimate the scope so stars are not perfect. This shows the bright orange star Eta Carina 8,000lyrs away at 100 solar masses ripe for hypernova explosion, its outburst in 1843 can be seen in the long FL image with the mintron ar F19.5 (6,800mm) showing two clouds of material either side. This star could go hypernova at any time and is currently at mag 4.6.

Ha=17x2min

O3=10x4min.

Mapped RGB with Ha O3 combinations.

Mintron F19.5 image is Ha+R RGB (Astrodon filters) taken last year.

Thanks for looking, John.
