Description

One night's work !

I need to sort out more images but here you've got 40 subs ;

34 are 105 sec @ 3200iso ;

6 are 140 sec @ 2000iso ...

>VERSION E : same as D, just a little more crop : I generally prefer wider fields but I'm proud of the details I caught on the Iris, so let them shine ;-)

>VERSION D : added 4 subs in Ha, 450 sec @ 3200iso ; looks a bit too red but for now, I don't find a solution.

>VERSION B&C : trying to bring out more details and contrast. Version A felt more "natural" in the editing process. Probably not enough subs here to push it so far, but hey ! I'll hit it again soon.

Enjoy the nights
