Very jealous! That's wonderfully done. Something is messing with my head a bit, where is the structure called The Pillars of Creation? Am I just not seeing it?

Thanks for your comments
Pillars of creation are located in the centre of the imagers the blue region , one dark pillar and one faint pillar
Unfortunately I’m only using a 1000mm focal length not exactly Hubble type image but you can see them
Clear Skies
Thanks
