My first attempt at these. The online resources are a big help. Turn off Long Exposure Noise Reduction, F11, ISO 100 and use bulb mode w/a remote shutter release. Biggest challenge, other than finding a good unobstructed view, is knowing when to open ahead of the bursts and when to close upon completion of display. Nikon 7200, Sigma 24-70 at 70mm.
