Robert, I guess no fireworks can compete with aurora borealis!
Well done!
All the best!
Thank you Jakov, In fact several fireworks did compete, only a hundred meters from us! But by the time I had grabbed the camera on the tripod, re-aimed it and altered all the settings, the display was over.
This was another display much further away, a minute or so later which I did manage to grab, if rather badly...
