i'm not a fan of all NB images but this one definitely works for me. beautiful, subtle hues through the middle of the frame and great tonal contrast as well. expertly processed indeed. without looking elsewhere i imagine it could look quite dull in true colour?

Cheers Phil. I agree, narrowband isn't for everyone but it sure does extract what are almost invisible features compared to broadband RGB data. The aspect I enjoy with narrowband is in the act of processing. It is a refreshing change to processing RGB data sets. There are a few RGB images of this target out there but you're right, its not a profound as a narrowband palette. Thanks for the feedback.

I know very little about long f/l astro-imaging let alone narrowband and generally comment on something I like. It seems I can keep looking at this image forever - a very aesthetically pleasing result.
Thank you!

Pleased you liked it Alex!
No need to bother yourself about the various aspects of F/L astro imaging to appreciate an image
Thanks for checking it out.

Cheers Marc. Yes, I tried to avoid the electrifying feel with a heavily saturation boosted colour layer. I really toned this one down to see how it would turn out. There are parts that could do with more saturation I feel, but it then results in an imbalance between areas. The resolution of the Ha and SII data was a real treat to work with. Thanks again.

Thanks for the feedback Rolf. Appreciated. Too much time put in one could say!

Very nicely done and those fast Newts when they work are an impressive machine.
There has been an interesting thread by Massimo Ricardi on the Astrophysics website and there appears to be a number of very fast (F3.6 or less) large aperture astrographs being designed.
Imagine a 600mm F2.8 astrograph?
In the meantime the ASA16 if it works would be a nice substitute.
For narrowband the U09000 might even be better with that bit extra QE
or better still a Proline 9000 as then you get the RBI control you need with that chip. Come to think of it Apogee brought out an RBI fix as well.

Cheers Greg. Yep, from up north in Cepheus. My gallery has targets from both hemispheres. Why restrict yourself I say!
The 16" ASA is located in Texas. John acquired the data on this one, but I would normally control his scope remotely to get the composition I'm after. I've got another data set to process, but will not get around to it for a few weeks (working on another imaging project at the moment - not enough time in a day!). Corrected fast Newts are great, but are finicky to tune. John has had his fair share of issues and tweaks to get this scope to sing like it does today. Apogee have had the RBI fix since 2007. Don't forget they've been shipping KAF-9000 and KAF-16803 chip camera's since 2006. Not exactly an new player in the CCD arena! Thanks again for your comments.

Thanks all for your support.
