SBIRSGEO3 Atlas V launch by United Launch Alliance

30 minutes of stars + 163 seconds of rocket: It was an amazing night for a rocket launch.

 

Seen here is the United Launch Alliance #SBIRSGEO3 satellite, launched tonight at 7:42pm (ET) atop an #AtlasV rocket from Cape Canaveral Air Force Station with great support form the 45th Space Wing at Patrick Air Force Base, Fla.

 

I had the streak ready within a few minutes, but this stack of star trails proved to be a bit more time consuming to process. The camera was running for nearly an hour, but a few early clouds and my own carelessness junked up a few of the frames, which of course I didn't notice until I started stacking. So this is the last half of the series, with a 4 mid-series frames removed.

 

Congratulations to the ULA team on their first launch of the year and for completing the first launch of the year from CCAFS.

 

Specs: 56x30-second exposure frames shot at ISO500 and f5.6 (trails) and then the streak is a single, 163-second exposure, all shot through an 11-24mm lens (at 11mm) on a full-frame body. Initial processing done in Lightroom, stacking done in Photoshop, with final edits done in Lightroom.
