Here's a link to the finished version of the Spider and the Fly. There was almost no oxygen in this area at all so I mapped the colors as follows: Ha=Red, SII=Green, OIII=Blue. Total time on this was 12 hours 15 minutes, all 900 second subs, except I added 15 minutes of RGB stars exposed at one minute each channel.
