Some of the time-lapse sequences I get take a lot of patience, sometimes waiting for many months for that few-minute window when hopefully the weather behaves and the camera doesn't freeze up.
I keep track of the relative positions of various local land marks, and compare them to  the local star charts to figure out when things will align.
Here's a few still shots taken from some recent work...

The cross on top of Observation Hill was erected as a memorial after Robert Scott and his men died returning from the Pole in 1914.


On the ridge to our north, the "Our Lady of the Snows" shrine is a memorial to Richard Williams, a SeaBee (US Navy) who died when his bulldozer broke through sea ice in 1956.


Locally the shrine is affectionately referred to as "Roll Cage Mary" because of the steel frame surrounding the statue.
