A once-in-a-lifetime opportunity, that’s what photographing Comet Neowise over London (or anywhere else, really) is! I’m not going to dive into too many descriptions of the event. I’m sure you all know about it by now.This is a once-in-a-lifetime event because the comet was only discovered last March, and it won’t be visible again for another 7000 years (seven thousand!). You still have plenty of time to witness it, as it will...
