Description

Last night after too many nights, at 2:00 am, the sky finally opened up a bit - with a poor seeing of 2 out of 5 ! It shows in the poorly detailed acquisition ; but hey ! I had to start on this "Hubble palet" journey !

> RULE number 426 : don't drop too quickly your data, there may be more hiding in it ! I didn't believe it could reach this level. This is by far my longest editing journey - maybe 7 hours trying to balance layer after layer, cleaning pixels almost one by one ! My reward is up here in ...

SUMMER UPDATE :

> VERSION F : I almost forgot this target in need of O-III and better Ha, so this mid july, I gave it a little time with 1 (!) extra Ha sub of 750'' @ 3200 and 4 x 600'' of O-III same iso...



> VERSION E : more then this means better seing + quality O-III subs + much better SII subs...

>VERSION C : from B, adjusting selective colors... the colors I had in mind are not quite there yet, but it's more like it.

>VERSION B : the SII channel was too weak and blurred so I did what I could, blending it with some broadband and making it "synthetic yellow"...

O-III : next time ;-)
