I combined 54 20-second exposures of 2012DA14 passing through Ursa Major into a timelapse video, complete with a couple of small bits of cloud crossing the view. I'm not experienced at doing video with Photoshop, but was impressed I could use curves and levels just like with stills. I've hosted the rendered video in Photobucket, which I've also not tried before, so hopefully this will all work.
It's meant to play back at 5 frames per second. You can see as the stars drift that my tracking mount was not well aligned. I must work on that.
