I saw a beautiful image of this object on Astrobin a few days ago and decided to try it myself. I agree with the person who posted that image (user 1074j) that this is a beautiful object that is often overlooked because of its proximity to the Lagoon and Trifid nebulas. It has a nice combination of emission, reflection, and dark nebulae along with lots of stars. I synched the PicGoto on λ Sag, and the goto was right on. It was a very warm night; the CCD started at 30 °C but 2.5 A in the Peltier cooler got it down to 18 °C. Once again I followed the sky background and general image quality using DSS Live. There were wind gusts, but they didn't hurt me much because I used a focal reducer to expand my field of view.
