Last night I was able to gather 2.5 hours using each of the OIII and SII filters; the total integration of the image is 8 hours. Likely it could benefit from more data, but it's a decent product for now. I was quite amazed at the amount of data in the integrated masters for these channels, as the subs didn't look like much.

This is the SHO rendering of the previous;y posted image. Still need to learn to use PA to remove the magenta and get a better light blue.
