Canobie Lake Park Saturday Night Fireworks part 2

This is the third effort to pull-focus fireworks. (The first was the Derry fireworks, the second was the Saturday night fireworks at Canobie Lake Park.)

My plans for a tripod were thwarted, and at least most of the previous ones weren't edited (besides cropping). In this cases I've fiddled with a lot of them. I also used an ND8 filter this tine (which I guess is like 3 f-stops down?) so I could open the aperture more, but it looks like it ruined the bokeh. Not sure if that was due to dust on the filter or the filter itself. [After cleaning the filter & comparing to no filter it's obvious that the filter disrupts the bokeh.]
