Made it down for sunset and had a little line of sunlight as you'll see on the sunset shot. But not long after sunset, we got a show in the other direction. Best on black if you have the time.
@cwbill Yeah, it was a long shutter speed, but not using a lightning trigger. Just get down to about f-20, and then start doing 15 to 20 second exposures and hope that it flashes across. It's always the best after sunset, when it starts to darken, then you can go with 20 to 30 second exposures. Just keep clicking and you'll eventually get the flash.
