Description

From my imaging location, M8 never gets more than 25 degrees above my southern horizon. So, I had not previously attempted to image such low targets. However, my success with the Lagoon Nebula prompted me to try the Trifid. I only had one night in August to work on the Trifid, so I shot 5 minute, unbinned RGB subs. Clouds rolled in just after midnight and shut me down. As a result, I was only able to get 8 subs in each filter. Normally, I would not attempt processing with only 8 subs but since it would be next year before I could try the Trifid again, I decided to process what I had. The results were better than I expected.
