From my Melburne surburban backyard, last night, during twilight, with a neighbour's bright outside floodlights lighting up everywhere, I was enjoying Saturn with the 9mm Plossl that came with my 8" f6 scope, using a Bintel 2x barlow. I calculate that to be around 267x. The image swam a bit, but the Cassini division was easily seen as was planet's shadow across the rings. Venus, much lower and in hazy cloud (that soon enveloped Saturn) was much worse.
According to the light pollution maps mentioned elsewhere on the Forum, my backyard is smack bang in the "orange" and closer to the "red" (worst) than the "green"!
I was happy with that performance!
