Description

Here is NGC 3247, also known as GUM 29 and RCW 49. The open cluster in the blue blob of OIII is Westerlund 2. Apparently, the nebula’s common name is the “Whirling Dervish.” This image uses the SHO (Hubble) palette.

NGC 3247 is rarely imaged. I haven’t found any other published professional or amateur images like this one.

I have been wondering if I could improve on the SHO version of the Whirling Dervish Nebula ever since I uploaded it. That portrayal just didn’t capture the ephemeral, fragile nature of this beautiful object. This revision has been completely reimagined. It’s based on the OSH palette and I hope you like it.
