Is the Skycreamer open over winter on the South pier?
You'd need a strong grip on the camera, and pressing the button at 5Gs during the 2 seconds it takes to go up might be tricky... but you with a little luck...
Nah, far simpler to use a 4K camera strapped to your wrist (like a Nintendo controller) running in video mode to get a single frame, that's what I did to get decent shots of Derren Brown's construction site, shame none of them ever saw the light of day after the dressing down I got on another site for daring to post one.
