Background noise- Not sure where to go from here

[Lightpath]

Hey all-

I'm very new to processing, and I've been following the Light Vortex tutorials.  I've so far done up to DBE, but I think I have some weird large scale noise and I'm not quite sure how to deal with it.  If anyone could suggest some tools to try next to deal with the background I would really appreciate it.  Again, I'm very new, learning as I go.  I'm not new to the hobby, just to processing.

Also, any thoughts on how to improve my data at acquisition time would be very helpful.  I image in a very light polluted area, so I'm taking 14 second images (TONS of them) with a CLS ccd filter, and then my plan is to use 60s narrowband images for colour.

Thanks for any suggestions!

The only way I could get a decent image with my current skill level is by using imgur, so here is the image and it looks pretty representative:

Hi,

Drop me a mail and I will send you a small text document for basic processing of images.  This will go a long way to producing a decent image.
