The K1 astrotracer seems to have a rather limited interface, with no real guidance compared to the hot-shoe version. I'm probably missing something obvious, but I feel completely in the dark (sorry

) when I'm using it.
Essentially, I turn on gps, set the camera to bulb, calibrate the astrotracer, then just hope it's doing something.
I keep trying to shoot Orion as a test, but I'm still not satisfied. The shot below was taken hastily outside the house on the road, with the K1 and 300*, 1600 iso, and my finger on the shutter for 24 seconds! I got away with it just and it seemed to be tracking here, but other times the stars are streaks - notably last night with a remote release, from the comfort of my son's bedroom while he was on his computer - magnetic problems?
