Description

This image is a blend of 60% RGB with 40% HSO. The RGB masters are hdmi composites of 21x60 sec and 14x300 sec subs. The HSO masters were hdmi composites from 12x180sec and 18x300sec subframes. This totals at about 6.5 hours. Challenging because of the bright Dallas Texas sky to the south. I found that having the Ha data was very useful for picking true back ground for just a few points for gradient corrections. Also blending the HSO into the RGB tended to suppress the gradients a bit.
