Astro-Photography Fail!

So, last night I was bored.  After I took my dog on a late walk, I looked up and saw that the moon was not seen and the stars were relatively bright.  Since I have my new 24mm lens, I wanted to see how it would work on astrophotography.

So, I did some research on YouTube – the great source of all knowledge – on astrophotography.  So, I am ready to make some photos like this, right?  Ummmm…  no.

I mounted my Canon EOS Rebel T3i to my tripod, set up my external shutter release, and set up the camera – ISO 400, f/2.8, BULB.  I experimented with several exposure times: 30 sec., 1 min., 1 min. 15 sec., and 1 min. 30 sec.  At 1.5 minutes, my exposure was already experiencing star trails.  That was not what I wanted.  I backed off to 1 minute 15 seconds, and I still saw that.

I have heard of light pollution, but i did not understand it’s affects until last night. Clearly, light pollution affects astrophotography in a big way.

Here are the results.  Those lines in the images are airliners on approach to Atlanta airport.  I live on their approach path.

Here is what I learned.  You have to be in a place that is so dark you would get lost with a GPS.  I can’t capture the stars at more than a minute without creating unwanted star trails.

I have a lot to learn about astrophotography and need a lot of money to get to the places where I can take those pictures!

On to the next!
