First light 3nm H-alpha M16

We have had this 3nm Astrodon H-alpha filter for a while, but have not had a chance to try it. I did get to swap it for the 6nm last month, but had too many other new things going on to try it until a couple of nights ago. I had planned on finishing the M17, but the guide star for M16 was too good to pass up. This is "only" 90 minutes, and I haven't decided if I should add more time, or just move on to different objects or filters and call this one done.

Thanks for looking.

Wow, looks real good to me Charlie. I suppose the expectation is better contrast with the 3 nm over the 6 nm. I know I am asking a subjective question here, but how much do you think it is improved?
