Description

I experimented with various approaches to visualize the cross-hatching of lanes in this beautiful, faint nebular area. For my taste, the Ha (monochome) shows the most subtle detail and is aesthetically pleasing. That said, I like the bicolor too. The HaRGB, however, did not really work. I combined RGB data from a Canon 70Da with Ha data from a ZWO ASI1600MM Pro. The result is bloated stars and a soupy look to the nebula. I need to rethink this technique. Probably better to use RGB data from the ZWO ASI1600MM Pro.

Add an additional 3 hours of Ha data. It really helps refine the details.
