Did see about 3 shooting stars, when changing lenses... before the clouds came in, they were late or there wouldn't have been the lights! From about 11:30 until nearly 2am Sunday Night/Monday morning I took a series of Time Interval shots and used mencoder on Linux to put them together into a video. You can create a time lapse by setting your camera up on a tripod (I moved the camera because the northern lights moved from the north to the south which was toward my east). Ideally you would use a camera with the feature. Try to avoid using the feature where it creates the video in the camera as you won't have as much control over frame rate and you may not have individual pictures to work with. Most of the exposures were around 2 to 3 seconds, I set the aperture to f2.8 for the 14mm shots using 2500 ISO with a Nikon 14mm f2.8 AF-D lens in manual focus mode, set to infinity... (I like AF-D for this reason) The shutter speed may have varied as I used Aperture mode. The pictures were NOT edited, so when the pictures get dark it's because the intensity of the Northern Lights had reduced. Towards the end as the lights began to fade, the clouds moved in... once they fizzled out I switched over to my Nikon 16mm f2.8 AF-D and tried to catch a shooting star... all I got were swirling clouds... HOWEVER, I did see one meteor to my right... and then when the clouds came in I could see flashes of light here and there, like lightning, but it was meteors above the clouds!! Got skunked on meteors... I think I saw one in front of me, but it was when I was changing lenses. I was hoping that in all these time lapses, taken 30 seconds apart, that I'd catch one. But the meteor shower picked up about 1am or so, right when the clouds had arrived. I thought about staying up longer, but the number of meteors per hour expected just didn't seem like it was worth it, especially since I couldn't get those cool streaks of light on "film". Here's the basic script to use with mencoder, you can change the frame rate as desired. Hopefully posting this script won't trigger some bot filtering out potential malware... enjoy. (I recommend Linux MINT MATE, it's the best of the Debian based distros - but any Debian based distro is fine, MINT MATE is just very stable and has a very functional desktop, and is quite happy running Oracle Virtual Box VMs so I can use old school XP free apps for basic work flow... I need to learn DarkTable (open source and on mac & linux).
