Melotte 15 (The heart of the Heart) in Hα-SII/OIII/OIII+rgb

www.astrobin.com/y3jzyf/

The heart of the Heart nebula revisited using the "natural palette" with special attention to the dark nebulas there.

 

It a complete rework of a previous image made on SHOrgb.

A total of 57 hours of integration and a lot of intermediate version on the process.

 

Still I think that I could obtain more details, but this will be next year (maybe :P ).
