I've taken better lightning, but for a ton of light polution in town, I managed to pull this off. I just took it a few minutes ago, but I'll play in PS to make it better! I was using a TC-80 N3. I set the fstop to 4.5, the iso to 200, focus to infinity and my timer to 20 sec and just kept hitting the stop start button. If I saw lighting i hit stop. This kept the light from blowing out my frame and still kept the lighting bright when it would hit. Hope you enjoy! As much as i do.
P.S. This looks awesome at full res!!!
