These have been mentioned a couple of times before but I haven't seen any real attempts to produce them in TG. They have been on my "To try", list for a while as I often see them on clear nights around mid-summer. Two things brought them to the top of my list; first Oshyan posted a link to a web site documenting all kinds of interesting atmospheric phenomena.

Second j meyer used and was kind enough to share a Cloud Density Fractal that looked promising, this was in an experimental thread using vectors passed as density input to a cloud layer:

Here is the result, the fine structure is not quite there yet but the colouring produced by passing a vector to the density input works well. I added the stars using a clip I downloaded from here, I have not been able to find it again so can't credit its creator. This is where the Comment/Null node discussed elsewhere would have been handy
The first picture is of some Noctilucent Clouds as seen from Glasgow around 01:30 June 30 2007.
C&C welcome.
Awesome clouds :P
Great re-creation! Your clouds look a little too warped compared to the ones in the real picture, but that doesn't make them much less believable in my opinion.
Really well done! ;D
good job !
agree with OB....less warping in needed......
good job!
well done
These are perfect. Beautiful work.
Brilliant...something else for me to work on now....sigh
Thanks for all the comments. ;D
I agree about the warping, If I do them again I will tone that down a bit.
I have some ideas about how to get the fine banded structure in these and other high clouds but will leave that for another time.
