Ultra deep Lagoon
Some more fiddling 
I worked on my Ha and Lum from my recent lagoon data set to see how deep I had gone.
The Lum shows up both dust and Ha while the Ha filter isolates the ionised hydrogen structures nicely
I have gone for a slightly dramatic contrasty look..for something different
This is 60min Ha + 120min Lum from light polluted inner Newcastle - there is extensive gas and dust around here.

I like that a lot Mike. Somehow the Ha introduces a really 3D effect.
Cheers

Cheers boys, yeh Johns work is the best Ha imaging out there Louie, of course mine is a Lum+Ha and the Ha filter I use is a 12nm where as John uses a narrower version I believe, so it is a little different result... my image is more like a mega-luminance

Yes cause Mike,It's more the distribution of brightness levels that reminds me of John's shots,although obviously John's have more contrast.

Yeh casue they have no dust in them only Ha
I only had 1hr of Ha so it wasn't deep enough even with 12" at F3.8) - I want deep, DEEP I tell ya! 
So I also used the 2hrs of Lum

I'd say you didn't pay attention to the oven timer Mike. Image has been cooked for too long. Look on the bright side, there's no blue cast. 
Gleason's AIC presentation from two years back had some great pointers for pure Ha image processing. Worth a look if you are so inclined.

Adds a new dimension to seeing this old favourite of mine in a way I haven't appreciated before. Marvellous!

That's very impressive Mike. It looks deep indeed. The Ha+L really shows off all the little knots and globules! Fascinating

Ultra deep OK. I quite like the contrast boost on this target. There is so much to look at and as usual you resolved even the faint bits very clearly.
Lovely image Mike.
