T-1 min.


Chosen the landing time to place the lander at local dawn (for a long period of solar energy), and with that, to ensure firing happens when the lunar temperatures are low.

Position of Chang'e 3 w.r.t. the landing site

wow! from that map it looks like CE3 is heading to the western edge of the landing site, and into Mare Imbrium, close to crater Le Verrier instead of Sinus Iridum

Appears landing box is large enough to land on subsequent orbits if needed?  Aiming at that edge would correspond to earliest landing window.
