Description

I was never satisfied with my images of The great Orion nebula, so when I finally got the chance again with (almost) clear skies, under the full moon i got the(bright???) idea that it is time to give the object (or myself?) a new chance.
With a shade to protect from the bright light from the full moon and stray lights from my "afraid of the dark" neighbours, I started to image the day before the full moon and finished the imaging the day after full moon.
I shot most of the subs under full moon , 85 subs

This is actually a difficult target at 60°N because the object is hanging low in the sky. Not only because the long distance the light have to travel through the atmosphere, but the light also have to travel through smoke and heat radiation from my neighbours chimneys.
Sub-arcseconds guiding is not possible for this area of the sky.
I discovered later that the subs in this images are shot with the field flattener not correct adjusted.

This time I did not shoot short subs but I found out the the same 180 seconds subs, integrated an moderately stretched, did a good job, as you can see in the "Revisions".
You are welcome to comment the image😀

This is a star birth region in and it makes me wonder if the ancient greeks got it wrong?
As far as I know, a male do not give birth to anything from inside the body,
Is it possible that Orion actually was female and the name is Orion the Great Hunter Princess?
