Always nice to see. What kind of skies do you have? I have to presume from your use of an IDAS LPS and also from the long total integration time of the image that they are not so good. I have come to realize that the best LP filter I own is the fuel filter in my car. Driving in my case just 45 minutes gets me out of the city where I can barely see the Milky Way at zenith, to mag 21 skies. The image below was taken in even better skies. It has coincidently about the same reach as yours wrt limiting magnitude yet it was a mere 9 minutes without a filter. (I also used a 6-inch f/5 telescope, so that helped too!)

I’m bordering a bortle 4 to the west and 5 to the east. I like the colors the IDAS produce. The integration time and everything else for that matter, is nothing more than a inexperienced imager experimenting. Thanks.

Then perhaps there is more in your image that can be pulled out with processing.
