Nice image Steve, very low noise look to it and I like the image scale.

I think you could achieve some banding with an IR685 filter, but I'm guessing you would need very good seeing as the exposure time will be relatively long.
There have been some good results with a 610 nm longpass as well, which might suit the sensitivity of the ASI120MM and allow a higher frame rate.
