I wasn't able to get out for any shots this year, but i too have shots of the ISS. That's currently my thing. As for focusing, the first time i manually set it to infinity then dialed it back the slightest bit. it was okay, but i've gotten better results leaving it at infinity. i'd like to try manually focusing using the magnified live view, but i'm either so hard pressed for time, or i actually forget that my camera can do it. the the 5dmk3 is my current camera. the 5d had been my most current camera and i forget about some of the bells and whistles i now have access to. I've mostly been shooting around f2.8/f4 iso800 30sec, usually always to the stop at the wide end of my 16-35. I adjust for clouds and ambient light and stuff. when i want longer exposures i use my kitchen timer! I just can't bring myself to drop another dime on something like that(the fancy timer release), besides at 30sec+ what's the difference between 40 seconds or 42?I've been back and forth for a long while now about selling my 16-35 to fund a 24mm 1.4, but so far haven't as there are lots of things the zoom can do that the 24 can't. either way it's a compromise, and so far i've just stayed put. so if i post a few ISS shots here under the meteor heading i won't get a spanking?
