Very nice job. You got plenty of stuff in there!

only thing I would say is, can you get a bit more S2 to come through, the image looks a bit green.

may I recommend the narrowband imaging yahoo users group. You can share photos there and get lots of tips should you ask.

Central blue is so beautiful with great outer arcs - S2 is always a problem but does not retract. Lovely result. John.

Wow that's alot of new images you present, thanks!

I really like the amount of data you got there, lots of details & noisefree!

Although it looks green to me, I had the exact same problem when trying to map my last pic in HST palette. I cut back the Ha down to just 20%, since it's so strong compared to the other filters. , & Ha as lum. What program/technique are you using to mix the colors?
