Hi,
This is an image of NGC 6357, also known as the Lobster Nebula, taken with narrowband filters and processed using the Hubble palette. Although known as the Lobster nebula, the FOV of this image is too small to see the entire nebula. It lies about 8,000 light years away in the constellation Scorpius. This nebula is home to open star cluster Pismis 24, which has some of the most unusually bright and massive stars in the galaxy. The intricate patterns are caused by complex interactions between interstellar winds, radiation pressures, magnetic fields, and gravity.
Comments and suggestions appreciated.

That TheSkyX issue was pretty common across the majority of planetarium programs. Now that the update for Windows has been pushed out, we can track on it (there were work-arounds when not tracking) but this is the last new moon cycle (until the moon comes up in the morning) to catch it before it is probably too low for us in the northern hemisphere. The forecast doesn’t look real promising.

Very nice. I had a shot at it from home in Oregon a couple nights ago and found it but the weather here shut me down. We are still not up and running at DSNM but should be in early December.
