Description

This is the HaRGB component only. Processing the luminance for this image is especially challenging because of the IFN....still working on maximizing IFN while controlling noise and star bloat. Will have that version up shortly. In the future I may try to get the IFN via RGB only. Overstretching just these few RGB frames clearly shows the IFN, but a the expense of much greater noise. So, I just processed it out until I get the luminance right.
