I have some images up on Astrobin now from the mono camera. If you care to have a look just follow the link below (there are few in the top row of my public gallery). Be aware that I hate the processing side, and this narrow band stuff would surely be done better by a pro but its a first step.
Four of the images on the top row of the gallery are from the mono camera, in narrow band.

These downsized thumbnail ones are alway bad.
