That's awesome! Just noticed a little bubble (planetary) in the reflection nebulosity right at top of image. Never noticed it before.

Such a dynamic area, would have been a pain to process with those HUGE bright stars! Love the colour!

Huge image with great colour. I really like looking over the transition areas between the emission and the reflection nebula.

Thanks everyone !
We're glad that you enjoy this one ;)

The process has been quite tricky because we had to make the two fields match together. And as you see, one part is mostly red and the other is mostly blue.
Actually, we have made exactly the same process for the two fields... and yes, the bright stars have added some difficulties to the process :)

Bye bye

PS: troypiggo: I think this is a reflection... :question: sadly

Outstanding effort! :eyepop: I know very well how faint that nebulosity is. Has to be up there as one of the best shots at this area I have seen. Well done:thumbsup:
