Description



> D VERSION : after weeks of computer in store to fix problems, here is a little photoshop reprocessed "let's make it shine more" !

> B Version : finally got round to fully reprocess and add latest summer subs... 1600iso gets definitely better result with little number of frames.

> A VERSION : after much time (over 2 month), almost forgot to reprocess this image, with better experience with filters and new O-III & Ha subs ; I did use the original image as a base and only partly reprocessed... Next year I may give it another go from scratch, but for now...

DATA :

Ha : 14 x 240 sec @ 6400iso (yes sir ;-)

Ha : 4 x 470'' @ 3200 iso

Ha : 5 x 900'' @ 1600 iso

O-III : 4 x 450'' @ 3200 iso

new O-III : 4 x 900'' @ 1600 iso

Broadband : 12 x 140 sec @ 800 iso (does work better on the bubble itself then my usual 3200 : Moonrocks you've got a point here ;-)
