Re; the Nagler and dancing "fairy" light. I get it too when I use the 13mm T6, especially in the 8" f5. There's also a fair bit of scattered light surrounding planets like Jupiter and Saturn. Don't even bother with Venus.
It's also (surprisingly) less forgiving even slightly off-axis, which was a bit of a disappointment at first.
But once you turn it on DSOs then the joy of this EP is revealed and I'm pretty sure that that is it's main function?
John (ausastronomer) can explain why, I'm sure.
