Description

The central area of the Heart Nebula, showing some of my favorite Ha structures.  An HOO combination, and still struggling a bit with overly blue halos to the stars, that result when I stretch the OIII data to pull more of it out. When not stretched hard, the Chroma 3nm OIII seems to match star sizes to the Astrodon 5nm HA really well, but as soon as I push the OIII more, the OIII stars start to fatten up.  Revision pending when I read up on better processing techniques for it.

Description: Went back out and grabbed 15x of each Red Green Blue to overlay RGB stars. This really helped make the stars appear more natural. There is still some residual blue halos, but the improvement so far over the original is much nicer.
