Wow! what an opening post!! Fantastic results...
I've not used a light pollution filter myself despite living in light pollution central, Brisbane. A lot of forum members use LP filters with great success..
From this point, I think the first thing on your "to do" list should be organising guiding. Guiding and running 5 minute exposures will increase your signal to noise ratio, providing cleaner "noise free" images.
The light pollution filter will definitely help being that I know a 5 minute exposure here in brisbane with a digital SLR produces a white image..
Its good to see you are fully calibrating your images this early in the game... I took my time to learn about flats/bias/darks, and my images suffered due to this...
Welcome to Ice In Space mate...
Great images.
