The Whirling Dervish Nebula- NGC 3247

I imaged this object way back in May 2009. At that time I found no amateur images of this object. In fact, catalogues listed the object as a galactic open cluster - and Hartung wrote that John Herschel had made a mistake in describing this object as " a decidedly nebulous group". Well Hartung was clearly wrong, and there is plenty of nebulosity here.

And in possibly an extreme case of pareidolia I saw a whirling dervish- and decided to name the object accordingly. Of course I posted my image - and floated the name here on IIS.

12 years later i revisited this target over the course of several nights in April, capturing 16 hours of data- and here is the result. Can you see the flowing twirling skirts? the raised arms? the turban ? I cant unsee this - and stand by the name!

I see this name being used by other amateur astronomers as well, so it does seem to have caught on- though some seem to have trouble seeing the whirling dervish. Come on surely itís nowhere as bad as the Running Chicken is it ?

anyway its a really interesting area and not often imaged, though much more often these days than in 2009 especially here on IIS

Comments and suggestions welcome, thanks for looking.

Great background story and image Narayan; wow that's quite a legacy as the name has certainly stuck. ANd in your image the way you have orientated it, it is a clear as clear can be... I think many image this 90degrees to this and that may be why it's not seen. And I agree with you on the running chicken, that one is mad... still cant see it ;-)
