Looks like a modern painting Carole!

You're not far wrong Hugh, Salvador Dali springs to mind, or even Picasso.  I struggled with this from a colour point of view and even tried Bicolour, but in the end this was the only one I felt showed off the nebulae sufficiently.

Thanks Duncan and Roberto, I was a bit unsure about the colour but now I have had your feedback and 54 likes and comments on Astrobin, I am feeling more relaxed about it.

On a re-think, probably more 'Impressionist' with those colours. :D

Great image Carole, the colours are a bit bold but it seems to work.

Thanks Robert, I was having difficulty controlling the yellows, perhaps I should have started over again.  But when it was used in the mosaic, ICE software toned it down to match the Sadr Region section, and it looks much better in that, although i can't claim credit for that.

It's so bright it hardly looks like space at all!
I love it.
The enormous range of nebulosity you have captured is terrific.

That image is a thing of beauty.  The colours are wonderful and the Crescent Nebula is highlighted really well.

It's an outstanding result!

Thanks Mark, I always value your opinion and had been a bit dubious about the colours.

Oh Wow!

I got a TOP PICK for this image on Astrobin, my 2nd Top Pick EVER, the previous one being my Seagull nebula back in 2017. 

Funny thing is, this image wasn't even a planned target, it was just something to fill in the time while waiting for my chosen target to rise above the rooftops.  (Bat and "Squid").

Just goes to show.

Well deserved, I think.

They all go in the calendar list Hugh.

Currently waiting to hear what the committee wants to do regarding the 2021 calendar.
