Description

I am impressed at how effective the narrowbandfilter is at suppressing light pollution. This is looking back over my city sky which is awash with light thanks to car dealerships which never seem to shut down.

On the negative side I was not able to bring the subs into sharp focus. Not sure why. Seeing probably.
