Hi Rob,
Yes, that's the one I'd probably choose as well. I have a sheet of the stuff, to make my own for a telescope or two, but I've had it for a while and I'm wondering if it's still safe to use.
The Sky-Watcher filter appears to snap on, perhaps. In any event, it must be attached most securely, in case the winds blow, or if other forces attempt to dislodge it, during use.
