Indeed another good Ha image Steve.. I'm glad you're able to guide through your 7nm filter, I'll be giving my 13nm another go with the ST9 in a few days, and hopefully increasing my guider exposure time like you've mentioned in other threads will allow me to guide through the Ha filter also..
well done, as the others have mentioned, it does look a little soft/smooth.. are you applying some sort of noise reduction thats smoothing it out like this?
