I also went with the 13nm clip in so I could use it with lenses or scope and it is another barrier to dust getting into the camera.
I have had good results using it to enhance my RGB shots with another layer and I love having to option to shoot something when the moon is out.
I am still not sure if using it to shoot objects heavy in Ha is better exclusivly with the filter or as a combination with RGB or RGB only and making a greyscale out of the red channel.
