Description

This is a mix of Ha and SII data. I did not bother with OIII as there was nothing there that I could see when I took a test shot. As it stands, the SII is also quite faint, so the Ha is just super dominant.

I did the channels as:

R: SII
G: Ha 50% + SII 50%
B: Ha

Revision B shows the wider field - the parts to the top/right are heading into GUM-14.
