Description

Well it's probably a stretch of the imagination that the Whirling Dervish nebula on it's side looks much like a cow, but the banana nebula does look a bit like a crescent moon :-)

I originally imaged this with Ha, OIII and SII, but not happy that SII is contributing much and making processing more difficult, so in the end here I've just used Ha and OIII and processed as HOO.

Stacked by channel in APP and combined and processed in Startools with final tweaks in PS.
