Hello,
I am new to this group, and am new to narrowband imaging.  In fact, I'm working on my first narrowband image, a bi-color image of NGC6888 (Crescent Nebula).  I feel as though I have good Ha and OIII data with round stars and a sharp image.  However, I am struggling with putting them together into a color image.  It seems as though when combining the images the color gets completely washed out.  I've tried mixing different arrangements, all with the same result. 

You can see the Ha image here:  http://www.buckeyestargazer.net/New%20Image%202.html  It is 2hours in 15min subs through an Orion Eon 80ED, mounted on an LX200GPS.  The OIII image can be seen here:  http://www.buckeyestargazer.net/New%20Image%203.html

Any advice as to how to combine the images would be most appreciated.  Perhaps the best thing would be for someone to take the raw Ha and OIII images and see what they can do with it, then tell me what they did.  I'd be glad to send the images to someone willing to do that, but I realize that's a tall order!  Thanks in advance for any advice.
