Managing the screen during Timelapse

[bguthrie]

The feedback on the screen is not naturally helpful during a night sky timelapse, and drains the battery. Closing the screen stops the capture via intervalometer, so it must be open. The screen doesn't display the last image while capturing a new one, so it's only displaying an image between recording. If doing back-to-back frames the screen is always grey and on, so draining the battery but not offering value. 

I would prefer to either display the last captured image until there is a new one, or allow the screen to be completely off. 

Ideally, I would love to be able to view captured images from a physically separate device like an iPad wile recording. Touching the camera means bumping alignment and I believe stopping capture... neither an option.
