A bit of a quickie this one. Only 24 minutes after discarding the worst frames. 3 minute subs.
This is my first processing attempt with a new technique for me where I use the best sub as the base for a layer mask. I'm also boosting the saturation I normally use in DSS. I think that way I need to play less in Photoshop.
Edit: changed pictures to a lower res version so it wasn't JPEG'd so hard.
This is with the IDAS filter Kevin. These guys were right down in the murk, so I've had to do a fair bit to make the background even.
I've attached my older attempt at this region 50x 2minutes. It also used the IDAS filter, but sadly lacked flats - then I deleted the original subs... oops.
