Here is my first real serious attempt at narrow band. M42-Trapezium region and De-Mariners Nebula as well. It didn't quite turn out as desired but still pleased. I think I over-stretched it a bit and conversion to Jpeg isnt good either. Next time!!
Total of 108 minutes of data, Meade DSI Pro 2, Astronomik Ha, SII, OIII, filters in Hubble style palette, Ha, SII, Ha, OIII, Celestron 102mm, EQ6, guided with Orion 80ST and DSI Colour 1.
Thanks for looking!:thumbsup:

The Hubble palette makes for very different view - looks good. What was the relative weighting on the filters?

I don't believe it applies to narrow band according to what I've read on the narrow band yahoo group.

Gaud, you have a seriously good image (guiding, focus, detail, colour etc) buried in that awefull processing :P. I adjusted just levels and it jumped out. The posted res is a joke man, 21K ?????????. Do yourself and the image a favour, adjust levels, perhaps a little selective noise reduction and post at say 200k, everything else looks great :D.

Theres not much I could do at that res, you should easily be able to improve on my tweak. BTW, you handled the core very well.

Wow, Thanks for the tip! He he, I know nuthin, Schultz, about processing!!:lol:
I didn't go quite as hard on the levels as I didn't want to clip the black end of the histogram as my DSI mentor will deduct points! I must admit I had forgotten to flatten the layers, which is another reason It looks like it does. Will post another try later today,:thumbsup:

That looks better. Yes the original was washed out and also looks like some vignetting going on - did you use flats? If not you may be able to correct that with either Gradient Xterminator or using the gradient tool in Photoshop.
As Fred points out you've done a lot of things right there. Time now to start mastering some Photoshop/Processing skills. Wodaski's Zone System book is a great book and very helpful.

Thanks for the tips and comments. I will definitely look into Zone Systems, I know I need it.
I tried a bit of gradient and redone the levels after flattening the image. Good as I can do at this stage.:D
That's a great looking image, you've captured some nice depth to it.
Cheers
