|It would be really useful to know the Bortle sky conditions of the image. I would love to know who is getting great results from Bortle 8 skies. My equipment ED80, CCD Mono, EQ6, narrowband filters.|

SQM is an optional entry on the current acquisition form here and there is a converter from SQM value to unaided-eye magnitudes. Many of my pictures were captured under SQM 18,40 = 4,3 magnitude = Bortle 8.|

Yes, that would be nice, it may encourage people to share shamelessly urban imaging, which is a healthy occupation for humanity.

I always take my subframes in Bortle 8 conditions (between the City Center and the Harbour which results in heavy light pollution).|
With the help of narrownand filters it is easy to get pretty deep deep-sky images with 600 seconds sub-frames. Of course it is also a question of image processing.
