DDP is good at see what potential the data has - give it a try so you know whats possible, then try achieve a similar result using curves. Hope to see you finish this one off with chrominance data - the FSQ is delivering the goods. Top stuff. Well done.

The contrast looks a bit high to me so you are losing details in the bright areas so I would try and stretch it a bit too, try what Jase has suggested. I use DDP and Log stretch in Astroart4 to spread the dynamic range out but similar functions are available on other packages..as I am sure you already know.

Thanks for the comments Gents. I have just taken the original image and stretched it only using curves and a little shadows and highlights.
Not really sure if it's better or worse. Just new to Ha imaging and I'm not sure which way is the expected way to process such an image or how to really get the desired result.
Comments gratefully recieved.
