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;

June 15, 2011 Lightning

Tonight turned out to be one of the best nights I’ve had for lightning photography.  I was able to place my camera outside under the new awning over the deck and take a ton of photos.  Since this particular storm was so energetic, I was able to capture lightning in a majority of the photos I took.  Here are a selection of the photos I took tonight.

Connecting a Nikon D5000 to a Telescope

I’ve recently posted photos (also re-posted below) that I’ve taken of the moon with my Nikon D5000 connected to my telescope.  Here are the components that I used.

  • Total Cost: $41.65

Edit: For this to work, you will have to use manual mode (“M”).

October 12, 2010 Lightning Storm

An evening thunderstorm rolled through last night.  While I did not setup the D5000, I did capture the following with my phone’s camera.  You can see the youtube video of it here as well as still shots below.

Polly Crockett Days 2010 – Cowan, TN

It’s that time of year again for the Polly Crockett Days Festival in Cowan, Tennessee.  It was a lot hotter this year at the festival, but still a relatively good turnout.  They didn’t have a car show this year, nor did I see many antique engines like I did last year.  One person was back again with a hit-and-miss engine making ice cream.  One big new item this year was the Civil War Cannon Reenactments.  I took plenty of photos, as usual.  This set includes photos of one of the cannons firing.  They had two cannons, but from the top floor of the Cowan Train Museum I could only see one of them.  You can view the schedule of events here and browse my photos below.
