I am interested to hear what your experience has been imaging in the suburban areas with light pollution.

As I see it if you experience poor seeing which I think is more common in a suburban environment due to the many heatsink landscape (roads, buildings) then you would be better off with a shorter focal length to overcome poor seeing (the blur is less visible in shorter focal length images).

But if you are doing narrowband there are quite a few images that show you can use long focal length scopes so perhaps they reduce the effects of seeing a bit plus the light pollution of course.

I am not sure that F ratio plays a part at all.

If using a DSLR you need shorter exposures due to their picking up skyglow.

If using a CCD cam then shorter exposures than what you would use in dark areas and stack them so a low noise camera becomes a bit more important.

As far as filters go you've got the narrowband and you'v got Hutech light pollution filter (-IDAS light pollution filter).

Opinions?
