OK Fred understand now. 20 min exposures and lots of em...... I'll stick with the 7nm I think.
You could frame it up and down and save my neck a bit. I'm getting older you know.
Still a good result and 3nm really strips the stars down, I use the 5nm including NII line. Detail here seem tough to get looking at others efforts in Oz with the JetStream interfering. This is the best structure I have seen this season even though its quite soft.

Yes, 7nm sure lets in more photons, and goes deeper, but slightly less Ha detail. 3nm subs are noisier too. there are annoying trade offs either way.

John.
There are some subs from an earlier LX200 12" effort thrown in to reduce noise. Those subs were not as sharp, but had more signal. I was kidding about the stars BTW, I healed them out . Ill do this again with more RCOS data, much sharper, but its a bit of a "done that" sort of object so only when theres nothing else to image in my limited sky view.

Thanks Jase, removing stars is BS, but I get away with it ....... sometimes .
Back in fine form Fred - narrow band, narrow field, nary a star in sight.
I applied some of my weird Franken-Decon, lifting a little bit of the fuzz. Your license is waiting...
Amazing. You have some cool tools there Ivo. You've got a star rounder tool as well right?
Greg.
Yes. But let's keep it on-topic
One thing I'll say though is that I constantly feed ST images from IIS to fine tune the automated stretching algorithms. Funny thing is though, with Fred's images, they always come out as they came in, i.e. the computer thinks they're perfect! (and so do I).
...which leads me to believe that Fred, in fact, is an android life form of some sorts...
Pretty awesome!
