These pictures were taken during a flyover of the International Space Station on August 28, 2012. The one lesson learned from this set is that next time I want to take a series and stack them together for a picture that has the space station crossing the whole sky.

August 23/24, 2011 Star Trails
I took this photo tonight. I used the same technique as I did in the previous post. This one is about a 50 minute one. For some reason my SLR powers off after about that long. I will need to find out how to turn that off before making longer ones.

August 21, 2011 Star Trails
I took these photos last night with my Nikon D5000. I set it to take repeated 30 second exposures. I then overlaid the images using a command line bash script and Image Magick. The first is about 25 minutes worth of photos, the second is about 50 minutes worth.

I started with a the first image as the “../temp.jpg” as listed below. This could be a image from the series or a blank black image of the same size. Then I ran the bash code below to generate the images.
$ ls *.jpg | while read a; do convert ../temp.jpg $a -gravity center -compose lighten -composite -format jpg ../temp.jpg; done;
New Night Sky Pictures
Here are my latest night sky pictures. I took these December 10, 2009. The brightest with the star streaks was about a 30 minute exposure. The rest were around 15 second exposures with varying apertures and iso settings.
