Mirror lock-up is a function that's useful for astronomy photos. Basically, it locks the mirror in the up position a few seconds longer than it normally would before opening the shutter.
This allows any vibrations from the mirror movement to subside before the exposure is taken.

Live view helps with that, too -- as mirror already has to be raised to enable that. I think the most stable config is a remote + live view (especially if you have live view magnification to help focus better)... But
1000mm... Damn, that's nothing short of amazing. I don't think I'd afford anything like that soon. Have to make do with 300mm + x2 teleconverter so far. In other news, I missed a perfect opportunity last week (on 10th) when Neptune was almost as close to Jupiter as some of its brighter moons and they all together were just "below" the Moon... We were out o the city proper, where the air is way more clear, but my wife was against me taking bulky photo equipment...
