A nice gift for my birthday, immediately tried on the polluted sky of a seaside town north of Rome.
Canon 50f1.8 at f4 on Eos60D Central DS @-15° 16x300s sub 1600iso unguided on a syntha EQ3, using uhc filter (clip.on, it seem works fine!)
no darks or flat, but I like the result .
comments and suggestion are welcome
