30 second subs were starting to reveal some of the nebulosity around the core so with my scope ill start there I think and work to see what works best 
THere is no way i would get all that dust in the light pollution! it looks amazing from a dark sky! |
I was using ISO1600 as that is reputed to be the signal to noise sweet spot for that sensor. Anything more than 2 seconds and I couldnt separate the trapezium stars, which are already a challenge with the little scope and chunky pixels
Given you're using the LP filter, if your image is brightening it there could well be a good signal component to it. Longer exposures do tend to look quite bright on the camera screen, but it all gets dialled back during stacking.
