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.

this can be helpful also.. when you click on the map and the extended toolbar (the wrench icon) you can see the value.

darker is better..red is no gooood.

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.
