This was done this morning, begun at 2:45 am (or thereabouts). It's entirely possible that there is too much light pollution and I hadn't really considered that although I'm well aware it factors in. This is phase of the moon the previous day (taken before dusk) but it's long out of sight at this point
There are also city lights so the sources of stray light are plentiful. It's possible that a hood would have helped but I think if I really want to do this, it's going to have to be multiple exposures. Something worth playing around with now that DFS can be turned off.
The way this was done was my camera was mounted on the side arm of my tripod and passed out of the second floor window of my house. I didn't want to sit outside and babysit the camera for an hour+. It was very securely locked to the tripod just in case the mount failed (Think $2900 15' drop to the concrete OUCH!!!!!). A wireless remote used with the 3 second delay. If you look at the large versions you'll see movement at the beginnings of the traces where I had to walk past the tripod and slightly moved the floor. Come to think of it though, even the room light seeping through the window blinds may have caused part of this. Hmmmm.. That's easy enough to cure. I'll have to try this again if it's another clear night but modify the setup slightly..
