Thanks guys. I was pleased with the results. Lightning photography can be very challenging, but all the conditions fell together for me on this occasion!
I'm just home from being out walking in the stuff tonight

(doing a search and rescue for some overdue canyoners in Kanangra) and it got way too close for my liking - instantaneous light and noise!

Glad to walk away from it!
BTW the search was successful!

So I'm off to bed...
